    - Enlarging existing PE sections Hi, Introduction: ****************************** I am trying to extend an existing section of a PE, in addition to updating the â??DataDirectoryâ??ies and section RVAs I have to update the resources RVAs and the import and IAT/INT tables RVAs, as for what was just mentioned everything works fine. Still, it is not enough for an unmanaged program to work ( managed assemblies are satisfied with the changes just described ). The Problem: ****************************** Several assembler opcodes refer directly to the IAT: when executing an imported API ( of an external DLL such as Kernel32 ) the CALL opcode ( 0xFF15 ) refers ( by an RVA ) directly to the IAT, e.g. FF15[four bytes resembling the RVA to the IAT], this call will not execute properly if a section was enlarged causing the IAT RVA to change. To fix this all of the RVAs associated with CALL opcodes should updated as-well, this require doing some dis-assembling: 1. How can I find the starting points of any unmanaged functions in the â??.textâ?? section? 2 .How can I distinguish existing assembly code with some other metadata? 3. Is it possible to get from the CPU the assembly opcodes it supports ( and the size of each )? If so how? Is there a specification or is there some other way of extracting the supported opcodes directly from the CPU? Any ideas, suggestions or pointers would be appreciated ( please donâ??t direct me to the PE structure documentation found in http://msdn.microsoft.com/...

    - Data validity and timeliness with PCI bus master transactions My question is about data validity and timeliness with PCI bus master transactions. I have a bus master PCI device. The kernel mode driver programs the DMA controller on the bus master device to transfer data from the deviceâ??s memory to the hostâ??s system memory. When the transfer is complete (the deviceâ??s internal DMA FIFOs empty), the device generates a PCI interrupt to notify the host. At this point, the ISR schedules a DPC, which performs some handling of the completed transfer and possibly invalidates the cache for that system memory region. I would like to know at what point a PCI bus master driver can expect, with 100% certainty, the transferred data to be in system memory. Is it ridiculous to imagine that the ISR/DPC processing could happen before the host PCI bridge can shuffle all of the data into system memory? Am I being paranoid? I would like someone who has intimate knowledge of this process to either ease my concerns, or give me a little direction. Thank you, Lou Rohan Tag: Updated version of ezusb.sys ?

    - Migrate to amd64 I am trying to migrate a win32 Driver to a amd64 Driver.

    - Multiple Handles To A PDO Ok, I'm attempting to do what 100 people have posted about before, but I'll ask about it anyhow because the answers have seem mixed. I am trying to basically implement this product: http://www.mks.zp.ua/shared-serial-ports.php. I would like to do it by using a filter driver that creates intermediate buffers with independant pointers in the buffers for each of the connected com ports. Meaning: App1: CreateFile("COM1",...) -> MyFilterDriver[Buffer1] -> \\Serial0 App2: CreateFile("COM1",...) -> MyFilterDriver[Buffer2] -> \\Serial0 App3: CreateFile("COM1",...) -> MyFilterDriver[Buffer3] -> \\Serial0 However, I am running into the problem that I have yet to be definitively answered: How can I create multiple handles to COM1. Unfortunately, I have to make this TOTALLY transparent so I can't change the applications connecting to COM1. I have tried doing things like "Device->Flags = Device->Flags & ~DO_EXCLUSIVE" to no avail. And APPARENTLY, when you attempt to open the second connection, no IRPs are sent to the driver at all. NONE, WHATSOEVER ... I thought this was kind of weird. Well, I know one of you smart guys out there might have some ideas. Any advice is appreciated.... ugh, I should have stuck to Windows GDI coding. - Bryan Berns Tag: Updated version of ezusb.sys ? My version is 1.1 from 2001 / 2002 from cypress website Tag: 54745

    - DIFX 1.1 automatically starts drivers? According to the DIFxApp.doc: "For file system drivers, file system filter drivers and file system mini-filter drivers, MsiInstallDrivers starts the service supported by the driver if a system restart is not required to install the driver." This is the behavior I observe even though my .INF file specifically that I want the service StartType to be on-demand. Is there a way to let me decide when to start the service instead of DIFxApp?

    - IOCTL + XP SP2 In year 2000 I developed a simple Virtual Network Driver in order to exchange messages from/to Microsoft IP to/from my user-space application that performs my proprietary data-link protocol (on both serial ports and modems). IP exchanges messages with my NIC in the standard way and my application puts/gets messages into/from my NIC through DeviceIoControl() function. I use the same IOCTL method with 2 different NDIS_OIDs to put messages into the NIC and to get messages from the NIC. #define IOCTL_NDIS_QUERY_GLOBAL_STATS \ _NDIS_CONTROL_CODE(0, METHOD_OUT_DIRECT) The NIC was developed for Windows NT 4 (conforming to NDIS 4.0 miniport interface specifications) and it works also on Windows 2000 and on Windows XP. Now with Windows XP Service Pack 2 my application can correctly put into my NIC messages smaller than or equal to 278 bytes; when the application puts into my NIC messages larger than 278 bytes the messages that IP receives from NIC contain "dirty" information. What is the reason of this behaviour ? Maybe is it due to some kind of buffer overrun protection in Windows kernel message ? Thank you Paolo Puricelli Tag: Updated version of ezusb.sys ?

    - Not able to communicate using virtual com port Hello all, I am using a Triton board with linux-2.4.19-rmk7-pxa1 on it. I have compiled with serial-usb emulation support. When I plug in the usb cable with Windows 2000 as the host, the device is recognised and the driver usbser.sys is properly loaded. And in the device manager, one more COM port is shown with drivers installed properly. From the host side I am getting the requests - GET_LINE_CODING, SET_LINE_CODING, SET_CONTROL_LINE_STATE. For GET_LINE_CODING, I send a Linecoding structure. (115200, 0, 0, 8). For SET_LINE_CODING, I read the data into FIFO and then send a zero-length packet. For SET_CONTROL_LINE_STATE I just send a zero-length packet. But when I try to open the hyperterminal with that COM port, it gets disconnected and I am not able to communicate. So, I wanted to know what must be our response to these requests. Thanks for your time. Regards, mohan Tag: Updated version of ezusb.sys ?

    - How to add PID filter function in BDA driver ? Hi, I want to develop the standard BDA driver for USB1.1 device. But usb1.1 bandwidth no enough to transfer all programs of one frequency, so I need to add PID-filter function in driver to notify the USB firmware to filter unnecessary programs. I look for DDK and find a BDA property---'KSPROPSETID_BdaPIDFilter', it seem to match up my idea. But how to use the 'KSPROPSETID_BdaPIDFilter' property in BDA driver ? If it isn't for PID-filter purpose, has other method for PID-filter function in BDA driver ? (If use the proprietary property, the standard BDA viewer can't play the driver. ) Thanks, ShaqLee.

    - 1394 Device : Bus reset while installing driver Hello list! I am developing device driver for 1394 device and I faced somewhat unusual while installing the driver. My environment is as follows. OS : Windows2000 SP4 OHCI 1394 : TI chipset two 1394 camera First, if I use one camera, there is no problem. After I connected one camera(first) and install driver manual, I unplug the device and I connect another camera(second) and install driver manually. Now, I reconnect the first camera again. Then, the Bus Reset routine of the driver of the second device doesn't called. So, the second driver is not controlled properly, because the generation count is not correct. But, if I unplug the second device and replug it, it's Bus Reset routine is called. And all cameras working properly. I don't know why this situation is occurred. I think the sequence of the driver installation is same when I install the driver manually and when I replug. I tried to call REQUEST_BUS_RESET when the SRB_INITIALIZATION_COMPLETE is called, but the result is same. What am I supposed to do? Any suggestions will be appreciated. - James.

I'm using Compuware DriverWorks and I'm not sure where and how to implement the acquisition of resources. I found some tantalizing queries and responses on the web, but nothing substantial. My question: the DriverWorks library provides the objects KResourceRequest and KResourceAssignment. Are these to be used in the device object constructor or in the ...Device::OnStartDriver IRP response function? Are there any good example programs floating around?

    - Legacy serial mouse for Win2000 I have seriously managed to confuse myself. I have what I think is a simple task. I have a non-PnP serial mouse, which is NOT supported by serenum. All I want to do is install it on COM1. Reading this, and the OSR, groups, I have not been able to get my head around the right approach. I have successfully written 3 PCI WDM drivers. I have spent some time with Toaster and Serenum. Since my mouse does NOT respond to the serial PnP protocol, am I right that I cannot use serenum or sermouse? My mouse won't return the 'M' or 'B' when sermouse asks for; does that mean that sermouse won't work as-is for my device? Other than the durn 'M' stuff, shouldn't sermouse work, assuming that my mouse behaves "like" a mouse? If I could modify sermouse to create MySermouse.sys, could I somehow attach MySermouse.sys to the serial port device stack and then be in business? I have read Mr Oney's "Driver's for Serial-Attached Devices". I keep trapping myself in thinking that my situation doesn't fit because my device is just a mouse that won't PnP, and not some new thing. I keep waffling on whether I should create a root-enumerated driver that attaches to the serial.sys device stack, or a root-enumerated driver that somehow opens and uses the serial port, or a bus driver that creates some sort of PDO that is associated with my mouse and its serial port some way. I must say, this has forced me to look more closely at the W2k driver architecture. The OSR class, Mr Oney's book, the DDK docs, and the web have provided me with MUCH entertainment. I, however, have managed to confuse myself... Thanks for any advice. John Reilly. Northrop Grumman/Sperry Marine. Tag: Updated version of ezusb.sys ?

    - Error in PnP application with Rev_00 PCI ID - need help I am bery new to this PnP API world and will need help in troubleshooting a critical issue. I have a custom made application that uses UPDATEDRIVERFORPLUGANDPLAYDEVICES to install pnp video drivers. Application is invoked from a batch file and usage is c:\ <APP> <inf file with full path with driver files> <PCI h/w id>. PCI card is scanned with another utility and actual scanned pnp ID for the pci card to be installed is passed to the application along with the inf file as arguments. Application goes through the PnP installation process without any user intervention. The application works perfectly fine without any problem except for a ATI-X300 card that has rev_00, . The moment I try to install a ATi X300 card with rev_00, it throws me a dialog that says: "You must restart your computer before the setting will take effect. Do you want to restart your computer now ? Y/N " . For all other cards, it goes silently. Installation of the driver goes fine If I respond as "Yes" or say no and reboot later. Issue is I do not want the dialog which anyway does not come for other cards. Now, I want to know: Is there something specific in the MS PnP installation algorithim about pnP id that has Rev_00 ?

    - BUGCODE_USB_DRIVER with parameter 1 == 0x5? I'm working on a USB driver and one time, on a rarely-used test machine several days after the last time my device was attached, a user shutting down the computer encountered a BSOD with BUGCODE_USB_DRIVER with parameter 1 == 0x5 as the computer started to shut down. The online list of bug codes (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ddtools/hh/ddtools/BCIntro_f55acfed-3296-4e84-8885-c3162fd0ddbf.xml.asp) doesn't list 0x5 as a possibility for parameter 1 for bug code 0xFE (BUGCODE_USB_DRIVER), and DDK 2600.1106 doesn't list 0xFE at all in ddtools.chm. The other parameters were 0x81F200E0, 0x80862442, and 0x81F315B0. My driver does not appear to be in the fault stack, but it looks like I must have corrupted something somewhere along the line (maybe as I shut down my driver or my device?). So far this crash isn't reproducible but I'd like to know a little more about it if I can. Thanks in advance for any insights. -Scot Tag: Updated version of ezusb.sys ?

    - Default USB interface Dear ALL, I am working for company, which creates high-speed USB devices using Cypress microcontrollers. To reprogram Cypress firmware I need to send it several specially formatted USB control requests. My goal is to develop universal application and may be driver (if unavoidable), to reflash our devices during testing and in the field. It would be nice to have such application because firmware update implemented by Cypress microcontroller in hardware and do not depend on whatever junk we loaded it with previous time. I figured out, that all USB devices support interface with GUID {a5dcbf10-6530-11d2-901f-00c04fb951ed}, which is GUID_DEVINTERFACE_USB_DEVICE. Is there any way to get anything useful out of this device interface? I figured out, that it is exported by usbhub.sys driver and get created even if no driver loaded for USB device. I can open this device with CreateFile() Win32 API call, but that is all. I tried to open this link from one of my drivers and use the object returned by ObReferenceObjectByHandle() as lower physical device object to send URBs to, but it didn't work. As a last resort, I can develop USB filter driver if anything simple would not work for me, but I am not sure if I will get access to USB device without driver loaded. Thanks for reading my message :) I will really appreciate any help on the issue. Thanks for your time, With best regards, Vladimir S. MIrgorodsky Tag: Updated version of ezusb.sys ?

    - Performance problems 1394bus.sys Any suggestion on the following topic please: I am working on a project for a motion control architecture based on the 1394 bus. We are using the Windows XP 1394 driver stack and built our own custom function driver. Since the application is timing critical we developed methods to see what is going on in time inside this driver. We need continuous isochronous transport so we are reattaching buffers inside the driver. Strangely enough the time needed for reattaching (and especially detaching) buffers seems to increase over time. From about 30us for 100 buffers at the beginning of the transfer to 150us after a few seconds. Size of the buffers does not seem to matter, the number of buffers, however, does. This is a serious issue for us, since reattaching buffers now claims a lot of our system resources (CPU load). Is this a known problem? Is there a way to avoid this problem? What causes the 1394bus driver to spend so much resources on detaching / attaching? I will be glad to supply additional information if needed.

    - Trying to replace NdisMAllocateMapRegisters() with NdisMInitializeScatterGatherDma() So I figured that I would call NdisMInitializeScatterGatherDma() as the docs say that should let us get shared memory. But I get zero shared memory when I use NdisMInitializeScatterGatherDma() Here is my setup: ==================================== #ifdef MAPREGISTERS Status = NdisMAllocateMapRegisters(pAdapter->D100AdapterHandle, 0, NDIS_DMA_32BITS, // pAdapter->NumMapRegisters, 1, pAdapter->MaxPhysicalMappings); #else Status = NdisMInitializeScatterGatherDma( pAdapter->D100AdapterHandle, FALSE, 4096); #endif ==================================== When I undefine MAPREGISTERS I don't get any shared memory. Yes I set the bus master bit in NdisMSetAttributesEx() Yes I get NDIS_STATUS_SUCCESS from either call. Any ideas? Tag: Updated version of ezusb.sys ?

    - UNIDRV add custom paper sizes I am attempting to add custom paper sizes to a UNIDRV printer driver from a ui plug-in dll. Adding the paper sizes is straightforward usig AddForm. However the array of paper size OPTPARAM does not include this new size until the document property sheet is closed and then re-opened. I would like to have this array re-initialized with the newly added form without having to close and re-open the dialog. I have attempted to manually reallocate the array and add a new OPTPARAM to the array pointed to by the pOptParam member of the paper size OPTTYPE structure, although this seems to work it does not save the new form in the devmode correctly.

    - PnP INF File Question I have a VERY strange situation I need to solve. We mfg a serial hardware device for downloading data out of a reader. The downloader contains PnP code; when you place the device on the serial port, reboot or run the add device wizard, everything works fine. However, this PnP device does NOT require a driver, so we wrote the below INF file which seems to work fine. There is one catch I would like to solve, and perhaps someone knows how to do this. When we install the INF in the INF folder, we would expect the process to NOT query the end-user. This is NOT the case; the process is querying the user in all cases. Why is that? Is there something we need in our INF, or is it because we do not have a signed driver that is required? We would really like to avoid having the user have to constantly browse to the INF when it is already local to their PC. Any help would be most appreciated. Thanks!

    - Restricting access to USB devices Hi All, We have two requirements in our project, it is related to USB devices in WDM. We don't have much idea regarding the USB devices and USB class drivers. So I hope I can get some guidance from this group regarding my problem. Operating System : Windows XP Embedded. One requirement is, support only few specific USB devices in the machine. All other USB devices should be blocked. The following are the USB device classes to be supported in the machine. a. Human Input Devices (HID), b. Chip/Smart Card Interface Devices (CCID) c. Various Mass Storage class devices (MSC). E.g.. Smart Card d. Audio and Modem devices Our Current Idea for implementing this ---------------------------------------------- Remove the class drivers of the classes of devices to be blocked. Some of the classes we identified to be removed are listed below. a. Printer Class (usbprint.sys) b. Communications Device Class (mdismp.sys) c. Imaging Class (usbscan.sys) d. Hub Device Class (usbhub.sys ) This can be done while configuring embedded Windows XP. Will be there any problem if we remove these drivers ? The second requirement is that the read/write access to the supported USB devices should be controlled. i.e.. if it the permission set is READ_ONLY, only read access will be allowed. Our current Idea for implementing this ------------------------------------------- 1. Write a USB filter driver ( Say, usbmon.sys) 2. Install it as a 'class upper filter driver' to the required classes of devices. a. Human Interface Device (HID) Class. (hidclass.sys) b. Audio Class (sysaudio.sys) c. Mass Storage Class (usbstor.sys) 3. Export a IOCTL from usbmon.sys so that user mode applications can control the read/write operations to . Is there any better idea for implementing these things. Are we in right direction? Please advice. Thanks in advance, vasanth. Tag: Updated version of ezusb.sys ? My version is 1.1 from 2001 / 2002 from cypress website Tag: 54630

    - WDM Wizard Walter Oney Hello, I am trying to develop a WDM driver with the WDM Wizard that comes with Walter Oney´s Book, I am able to create a project without or with generic.sys, and also I can compile them but when I install it in the system using the .inf file the Device Manager show that there is a problem with my driver, and the message is that: "This device cannot start. (Code 10)" I did not make any change in the walter oney´s wizard generated driver, so I guess it should work, without any functionality but I just want to see that is ok. There is something that is necessary to do before compiling, like adding some code, because I just have used the fixproj.exe that the book says to execute.

    - Set the postscript dirver option TTDownloadFormat ("TrueType Font Hi, I asked this question in 3 other newsgroups (microsoft.public.windows.print, m.p.w.print_fax, m.p.w.printing), but didn't get a reply about what I needed, So I'm trying here again. Any pointers to other newsgroups that may help will also be appreciated. I'm trying to write a program that creates a printer, with a driver based on the MS PS driver and a ppd I supply (it has to run under windows 2000 and XP). If I do this, the printer created has an advanced option "TrueType Font Download Option" (in XP under the printers 'printing preferences', then 'Layout/advanced/Document options/PS options/TrueType Font Download Option'). I'd like to set this option to 'Native TrueType' when creating the printer (or right after it). I have found no way to do this short of looking at which bits in the devmode's driver specific portion change and redo that change using GetPrinter/SetPrinter (I understand from what I read however that fiddling with the driver specific portion of devmode like that is a very bad idea). There seems to be a way to set this through IPrintCoreUI2::SetOptions, at least that's the only 'SetOptions' I can find that this article could be talking about: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_9c9f919f-341e-45bb-ab32-a8e215cecb41.xml.asp However, from what I understand, this call is designed to be called from a printer property sheet, and structures made available by the system that calls the property sheet (first parameter: "poemuiobj Points to the current context, an OEMUIOBJ structure.") Does anyone know a way to set this option? ---clarification based on earlier answer--- Note that this is not the dmTTOption memeber of DEVMode, that sets 'Layout/advanced/graphic/TrueType Font' (which has options 'Download as Softfont' or 'Substitute with device font'), while the option I'm looking to set is under 'Layout/advanced/Document options/PS options/TrueType Font Download Option' (which has options 'Automatic', 'Outline', 'Bitmap' and 'Native Truetype'), but only for printers that use the microsoft PostScript Printer Driver (Pscript, documented at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_ccdc3e30-0b44-4ada-b51a-8c0d0bfd5997.xml.asp). It is specific to Microsofts PostScript Printer Driver (I think), and is described as "Driver features are non-PPD features that are synthesized by the driver" here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_a64f2cd3-6775-4121-98b1-7470c302574f.xml.asp Thanks for any help anyone can give me.

    - Microsoft please help! NDIS Intermediate driver bindings We have written an NDIS intermediate filter driver that binds to TCP/IP at its upper edge and a network adapter at its lower edge. If another intermediate filter driver is installed as well, the new driver either sits above our driver or below it in the stack. Is there a way that I can force our driver to always be above the other intermediate - we always want to see the traffic coming directly from TCP\IP and not from some other intermediate driver above that might be above? I suppose the question I'm asking is, is there a way to control the ordering of intermediate drivers when there are several installed on one system? Tag: Updated version of ezusb.sys ?

This usually indicates problem with the hardware itself or with the device driver programming the hardware incorrectly. If the kernel debugger is connected and running when watchdog detects a timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx() and detailed message including bugcheck arguments will be printed to the debugger. This way we can identify an offending thread, set breakpoints in it, and hit go to return to the spinning code to debug it further. Because KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck information in this case. The arguments are already printed out to the kernel debugger. You can also retrieve them from a global variable via "dd watchdog!g_WdBugCheckData l5" (use dq on NT64). On MP machines it is possible to hit a timeout when the spinning thread is interrupted by hardware interrupt and ISR or DPC routine is running at the time of the bugcheck (this is because the timeout's work item can be delivered and handled on the second CPU and the same time). If this is the case you will have to look deeper at the offending thread's stack (e.g. using dds) to determine spinning code which caused the timeout to occur. Arguments: Arg1: 824fd6a0, Pointer to a stuck thread object. Do .thread then kb on it to find the hung location. Arg2: 82675ce0, Pointer to a DEFERRED_WATCHDOG object.

    - PREfast: pragma prefast The PREfast documentation seems a bit lax on the usage of pragma prefast for inhibiting display of individual warnings. It only shows how to inhibit Compiler warning 4068, but does not show how to specify the PREfast warnings. How do I use it in my source code? Can I use the pragma statements to turn a warning off before and off after a call to a function or macro (like IoSetCompletionRoutine) that always generates a PREfast warning (314, in this case)? Thanks for the help, Dennis In case any PREfast developers view this, I suggest looking at Gimpel Lint for effective ways to inhibit warning messages. Tag: Updated version of ezusb.sys ?

    - How to use 2 USB mice independently and simultaneously? Hello Experts :-), I am writing a Windows XP fun-application and would like to use 2 INDEPENDENT USB mice SIMULTANEOUSLY as input devices. Therefore, I understant, I have to go below OS mouse events (below mouse driver) as they all appear as coming from a single mouse. So, I tried to go through reading a HID-based device as described in the DDK. But I cannot get any data from a HID-based mouse. The reason is that I cannot even open a file by CreateFile (cannot get the handle to the mouse) cause this returns an Invalid_Handle_Value. What I think happens is that OS open a file earlier (at installing the device) capturing the handle and that only one file handle can be open to a HID based device, so the OS is the only one to be able to readall the HID input reports. Am I right? Or is ther a way to get input from mouse at HID device level? I see some solutions if I cannot access HID mouse from HID driver level: 1. At Windows level if there is some differentiation possible to see from which mouse the particular event came. But I doubt whether it is possible. 2. There is some way to overtake a handle to HID from OS. Whether stealing at the moment the device is connecting and drivers are interconnecting, or after the device is already connected. Somehow. I do not have a clue ho to do this. Any tips guys? 3. There is a filter driver needed below HID driver (HID mini driver? USB driver?), from where the mouse reports could be stolen from OS, or maybe forked? Would like to hear your opinion on that issue, Any help? Example code?

    - Using device drivers Hi all, I have no experience in device drivers developing / usage but I need to develop a program which controls a webcam. I guess I will need to use the device driver provided by the manufacturer, but I have no idea of how to do that. Does anybody know how can I find some useful information ??

    - Strange exception, please help I'm having a problem that I hope you can help me solve. My code is throwing an AV in the startup code in a way I've never encountered before. The instruction that causes the AV is: 006472E0 832D907FAF0001 sub dword ptr [0x00AF7B90], 0x01 The exception is: Access violation at address 006472E0. Write of address 00CC7B90. 0xAF7B90 is a variable in my BSS segment. 0xCC7B90 is outside of my address space. The code is in the initialization section of a 3rd party component which is called from the startup code, well before any of my application code executes. What I don't understand is how the above instruction could cause a write to an address different from the specified address. It seems suspicious that the addresses differ only in the 2nd byte. Thinking that I might have a hardware problem, I've swapped the CPU and memory in my computer, but the problem persists. I don't have a spare motherboard to swap in. This problem comes and goes depending on the address of the above SUB instruction. If I comment out a single line in my code, the SUB instruction appears at address 0x6472CC rather than 0x6472E0, and the instruction executes properly, subtracting 1 from the DWORD at 0xAF7B90. WinXP, SP1a+. TIA! Tag: Updated version of ezusb.sys ? My version is 1.1 from 2001 / 2002 from cypress website Tag: 54578

Hello,

can someone tell me if there is a newer / improved version of ezusb.sys then
version 1.1 which can be downloaded from cypress website ? I saw the latest
change was in september 2001.

I googled around and read, that on http://www.devicedriver.com/ they write,
you shouldn't use it for production because of bugs. Is this still valid
today or were the mentioned bugs removed from current cypress code ? Is it
worth buying a license ? What kind of bugs are inside the code ?

Another question on IOCTL_EZUSB_BULK_READ: I often see that as size for the
DataBuffer 0x8000 is used. Increasing it further to 64 KB seems not to work.
Why this limitation ? Is overlapped reading supported ? Any other ideas how
i can further increase bandwidth (currently 17 MB/s, with external IFCLK of
24,576 MHz) ?

Regards,

Martin

You can get a free copy of the latest ezusb.sys driver (V1.30.0.0)
from the Cypress web site.
http://www.cypress.com/cfuploads/support/developer_kits/EZ-USB_devtools_version_261700.zip
You will have to install the entire development kit in the default
directory, the source code and driver will be located in
"C:\Cypress\USB\Drivers\ezusbdrv".

I don't know of any "Bugs" in the ezusb driver. The driver has very
limited functionality. I think the only reason Cypress says that this
is "not for production" is that they do not want to take any
responsibility for this driver in someone else's product. One of the
limitations of this driver is that the IOCTL_EZUSB_BULK_READ in
version 1.30 is limited to 64K. Another limitation of this driver is
that it does not support overlapped reading. Cypress has always said
they have no plans to improve this driver, except to support new ezusb
chips, that "you should write your own driver" and that the exusb
driver is only for development purposes.

A Cypress app note for the exusb FX2 chip (usb 2.0) "Streaming Data
through Isochronous/ Bulk Enpoints on EZ-USB FX2"
"http://www.cypress.com/support/reference_designs.cfm?objectID=EDF665E8-CA56-4410-9B5CD3635BDF6275&tid=54A040FA-2262-424A-B14741267CBD1308"
states that the throughput will max out at 24MBps. To get this
high-bandwidth transfers it uses the CYdvk.sys driver that supports
three 1024 byte packets per microframe.
