 - manual install driver for pnp device I need to run a batch or a exe from inno setup(something like installshield) to install drivers for a Pnp usb device with FTD2XX drivers from FTDI. Now from a batch i call: C:\WINDOWS\System32\rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 .\ftd2xx.inf and i can successfully see the install dialog appear, all the drivers files are copyied in the right places, oemxx.ing is created, but when i plug in the device the same dialog appear and i need to reinstall drivers again in order to make it work. I noticed that after the batch, in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\ there is no Vid_0403&Pid_6001 key as expected So how can i full manually install this device without interaction with the user?

 - Communication via USB I am developing virtual console for a hardware board. it is supposed to work as a LCD for a target board. This would enable boards without LCD support to display on the desktop.The design is ready. Now shall I use TCP/IP for communication or the USB port.The advantage with USB approach is that every board has it whereas TCP/IP may not be implemented on every board. How should I start?

 - How to get started with creating a virtual filesystem? I would like to create a new virtual volume with a virtual filesystem, something that is visible as a drive, can be given a letter, and browsed in "explorer" etc., but where all requests to access files are handled by me, preferably delegated to a service in user space. What kind of component do I actually need to write, at a minimum? If I understand well, I would need to somehow create a fake volume and tell Windows (I/O manager?) about it, register my own filesystem and make Windows forward all requests to this fake volume to my filesystem instance, with which I would interact via ioctl. Is that correct? Could it be simpler? Is there a way to get there even faster with WDF? How about UMDF, does it have support for this sort of functionality? Tag: Windows CE USB Driver Tag: 76789

 - writing to the event viewer hello, i'm trying to write messages from my network driver in the event viewer using NdisWriteErrorLogEntry. in the driver i have the code: NdisWriteErrorLogEntry(Adapter->AdapterHandle, NDIS_STATUS_MEDIA_DISCONNECT, 1,0x001b); i also wrote a resource only dll with the entry 0x001c and an error string. i've modified the inf file to use that dll - the inf file copies it and in the AddEventLog.reg i've added it. but still, when i look in the event viewer i see a discription that says: "The description...cannot be found...use the /AIXSOURCE=flag....." but in the data i see my error code number. what am i doing wrong?

 - Device Object Hello I got a function now that is executed on the following line: DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = FilterDispatchIo; NTSTATUS FilterDispatchIo( IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp ) In this function the DeviceObject is a ControlDeviceObject or a the main DeviceObject. When it's a DeviceObject is passed through to another function that's passing the IRP to the lower driver. If it's a ControlDeviceObject it's going to look if something is send from the user application. In this check im looking if my own made IOCTL is send or not, if so i want to add an mousepackage. The problem is i need to main device to send the package to but at this moment i get the ControlDeviceObject all the time. I also tryed to save the address of the Main DeviceObject and use it when i needed to enter the package, but i think that isn;t even possible since maybe it has something to do with the Passing through of the IRP and the completion of it(what maybe would explain the error)? I tryed alot of things now and i im stuck now, can anyone help me on the right way in getting the Main Device Object so i can add my own package? btw the error that i got all the time was DRIVER_IRQL_NOT_LESS_OR_EQUAL. PCONTROL_DEVICE_EXTENSION deviceExtension; ULONG dwDataWritten = 0; KIRQL prevIrql; MOUSE_INPUT_DATA data[2]; ULONG inputConsumed; if(DeviceObject != ControlDeviceObject) { return FilterPass(DeviceObject, Irp); } deviceExtension = ControlDeviceObject->DeviceExtension; if(!deviceExtension->Deleted) { status = STATUS_SUCCESS; irpStack = IoGetCurrentIrpStackLocation (Irp); switch (irpStack->MajorFunction) { case IRP_MJ_DEVICE_CONTROL: switch (irpStack->Parameters.DeviceIoControl.IoControlCode) { case IOCTL_MY_OWN_IOCTL: status = Ioctl_BufferedIo(Irp, irpStack, &dwDataWritten); if (status == STATUS_SUCCESS) { inputConsumed = 0; data[0].UnitId = 0; data[0].Flags = MOUSE_MOVE_ABSOLUTE; data[0].Buttons = 0; data[0].RawButtons = 0; data[0].LastX = 0; data[0].LastY = 0; data[0].ExtraInformation = 0; data[1].UnitId = 0; data[1].Flags = MOUSE_MOVE_ABSOLUTE; data[1].Buttons = 0; data[1].RawButtons = 0; data[1].LastX = 0; data[1].LastY = 0; data[1].ExtraInformation = 0; KeRaiseIrql(DISPATCH_LEVEL, &prevIrql); (*(PSERVICE_CALLBACK_ROUTINE) deviceExtension->UpperConnectData.ClassService)( deviceExtension->UpperConnectData.ClassDeviceObject, &data[0], &data[1], &inputConsumed); KeLowerIrql(prevIrql); } break; default: status = STATUS_INVALID_PARAMETER; break; } default: break; } } else { status = STATUS_DEVICE_REMOVED; } Irp->IoStatus.Status = status; Irp->IoStatus.Information = dwDataWritten; IoCompleteRequest (Irp, IO_NO_INCREMENT); return status; } Tag: Windows CE USB Driver Tag: 76773

 - drivers for embedded graphics Hello. Anyone know anything about embedded VIA UniChrome chips? I want to run NT4 server on a CLE266 board with embedded UniChrome 3D. I don't care about 3D or video accelleration, but I do want something more than 640x480x4 resolution. VIA doesn't have an NT driver for the CLE266 board, but I did find an NT driver for an M400 board with embedded UniChrome Pro. Could that driver be used to set display resolution? (A VIA tech suspected 'no' but was not certain.) Barring that, how difficult would it be to develop an NT driver that provided no chip-specific functionality besides mode change? thanks, nf Tag: Windows CE USB Driver Tag: 76766

 - EngMapFile I have a mirror display driver that uses a memory-mapped file to push screen updates to an application that reads the updates from the file and sends them to a server for distribution. The user-level application creates the file and passes the name to the driver. The Driver uses EngMapFile to open it. Sometimes it fails and the application retries using a smaller size until it succeeds or reaches a minimum size and fails. I am guessing that EngMapFile fails because it uses non-paged system memory to back the memory-mapped file and since this is a limited resource there may not always be enough available for the full size of the file. Can someone verify this for me? The documentation for EngMapFile is very minimal. Thanks, Bill Wyatt, Sonexis, Inc. Tewksbury, Massachusetts. Tag: Windows CE USB Driver Tag: 76751

 - WPP tracing produces empty .etl file <apology> First, let me apologise if you are reading this twice. I posted this originally to the win32.programmer.kernel newsgroup before I spotted this one ! I thought this one might be more relevant. </apology> I'm attempting to use WPP tracing in my XP kernel driver. I've followed all the instructions at osronline and in MSDN, but I'm always getting an empty .etl file. I've added the WPP_DEBUG macros and I can see the messages being dumped to DebugView. Does anyone have any idea what I might be doing wrong ? Here is my tracelog -start call tracelog -start wavedrvlog -guid wave_wpp.ctl -flags 0x1 -f wavedrv.etl wave_cpp.ctl contains : d8580821-5d64-541f-aac8-c8dbaf80ea62 wavedrv And, finally, my WPP_DEFINE_CONTROL_GUID WPP_DEFINE_CONTROL_GUID(wavedrv,(E2E85950,7BFF,4ab7,8A0C,A1AD7AC8C1D5), \ WPP_DEFINE_BIT(WAVEDRV_DBG_ALL) ) I am concerned that tracepdb produces 2 .tmf files that do not match my GUID. Is this normal ? I do get a .tmc file which has the correct GUID. When I run tracefmt, it says it is using default.tmf and finished with Exit Status 38. I can't find any information regarding this exit status ! What does it mean ? Why is it using the default.tmf instead of my tracepdb versions ? For completeness, here is my tracefmt call tracefmt -o wavedrv.txt -f wavedrv.etl -p c:\tmf ("c:\tmf" does contain my .tmf files) After sorting my build problems out the other day, this has started to frustrate me even more. Am I missing something obvious ?? - WinDDK 3790 - W2k3 Checked Build Environment Thanks for ANY help/advice you can offer Cheers Ged Tag: Windows CE USB Driver Tag: 76750

 - Windows Server 2003 - Removing Reliance On USB/HID I have just recovered a Win2K3 install from an IBM XSeries onto an HP Proliant ML370 G3. Although the XSeries uses PS/2 keyboard/mouse I cannot log into the Proliant unless I use USB devices. This is not usually a problem, but I have 6 of these servers and only 1 USB keyboard/mouse. I could go out and purchase extra kit but I would like to try removing the reliance on USD/HID. Any ideas? D. Tag: Windows CE USB Driver Tag: 76746

 - Issue while attempting to retrieve the file object's path name associated with process section Hi All, We encountered a issue while attempting to retrieve the file object's path name associated with process section object after renaming the folder that contains the executable image. File System: NTFS OS: seems like all x32 NT based (2000, XP, 2003 & their SP) Steps to reproduce: 1. Create a new folder named "1" on disk (for example, C:) 2. Copy any executable file (e.g., "test.exe") to the created folder. 3. Execute this application. 4. Exit from this application (e.g., "test.exe"). 5. Rename folder "1" to another name (for example, "2"). 6. Execute the application located in this folder ("2\test.exe") that was executed at step 3. What did we get? The new process is successfully running, however we can't get the correct path name for the section object associated with this process, and also we got the incorrect path name in the PsSetLoadImageNotifyRoutine callback routine (see below example #4). As a result of querying the path name of process section we got: \Device\HardDiskXXX\1\test.exe Instead of expected: \Device\HardDiskXXX\2\test.exe We tried the different methods of getting the path name for the section object associated with the process. All methods, except the reading PEB give the incorrect path name:( Example #1. PSECTION pSection; .... get section for process executable image .... PFILE_OBJECT pSectionFile = pSection->Segment->ControlArea->FilePointer; ObQueryNameString(pSectionFile, ......); Example #2. Use IoQueryFileInformation for file object associated with process section object or use ObOpenObjectByName AND ZwQueryInformationFile for this file object Example #3. Direct scan file object fields and get file path name. Example #4. VOID NTAPI _PsSetLoadImageNotifyRoutine( IN PUNICODE_STRING FullImageName, IN HANDLE ProcessId, IN PIMAGE_INFO ImageInfo) { KdPrint(("Load image: %ws\n", FullImageName->Buffer)); } EXTERN_C NTSTATUS DriverEntry( IN PDRIVER_OBJECT pDriverObject, IN PUNICODE_STRING pRegistryPath) { return PsSetLoadImageNotifyRoutine(&_PsSetLoadImageNotifyRoutine); } Basing on PDB information (ntoskrnl.exe) the unexported function MmGetFileNameForSection that is called before executing load-image callback routine got the invalid path name also. What can Microsoft developers say on this matter? Best regards, Andrey Alekseev Development Team ISV System Safety Ltd. http://www.syssafety.com Tag: Windows CE USB Driver Tag: 76745

 - Unable to delete .sys file Hi All. I had posted this issue some times back. Can any one help me on this? This is the story: My driver is working fine as expected. But I am not able to delete the driver (.sys file) from drivers folder or overwrite it with another version , even after unloading the driver successfully !!!. Each time our custemers have to reboot the machine to do it !! Windows says,someuser mapped section is left, so I don't have the permission to delete it. I can delete the driver if I haven't run any user application on top of it. My driver code always runs and uses NonPaged memory pools. Driver is running on Windows XP machine with all driver verifier options enabled (of course without low memory simulation). It doesn't report any errors while I unload the driver. I could not see any resources left after unloading the driver (used Winobj, winmsd, process explorer etc.). And I haven't run Event Viewer. Can anyone suggest, how the application program can prevent deleting a driver file? Application interacts with the driver only through IOCTLs. It does not know .sys's name.

 - USB 2.0 High Bandwidth Iso I am having an issue with a USB 2.0 high-bandwidth iso endpoint. It isn't behaving the way I expect. The descriptor for the endpoint has the maximum bandwidth -- wMaxPacketsize of 0x1400, meaning 1024 bytes with 3 transfers per microframe. I had assumed that I would use this like any other isochronous endpoint, by sending it a series of 1024-byte packets, so that each microframe would consume 3 such packets. However, that does not seem to be what the host controller driver expects. I was VERY surprised to find that USBD_PIPE_INFORMATION.MaximumPacketSize was 3072, not 1024. Further, if I send it a series of 1024-byte packets, I get USBD_STATUS_INVALID_PARAMETER. It looks as though USBD will only schedule one URB per microframe. So why is this a problem? Well, let's say our data is coming in chunks of 2600 bytes, which means 1024 plus 1024 plus 552. We are using an FX2. Our data rate is lower than the maximum bandwidth. When the FX2 gets an IN token but its FIFO is empty, it does not reply. When that happens, I will get a packet with 1024+1024 bytes plus an error, followed by a packet with 552+1024+1024, but those bytes are all packed together. I can't identify the packet boundaries. So, is it a fact that USBD will only schedule one URB per microframe? Or have I missed something? -- - Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc. Tag: Windows CE USB Driver Tag: 76734

 - IOCTL_INTERNAL_MOUSE_CONNECT Hello I already got a working IOCTL that gives me the info i need from my user application. And now i want that every time i send my own IOCTL with an x and y values for the mouse to execute the mouse_callbackfunctie and insert a self made package with the x and y from my IOCTL.. Does it take much time to replace the IOCTL_INTERNAL_MOUSE_CONNECT (located under IRP_MJ_INTERNAL_DEVICE_CONTROL) that triggers the Mouse_Callbackfunction with a own made IOCTL? I get my IOCTL with help of an control device and in that control device i get my data with help of the Home made IOCTL. I hope it's possible to answer. Tag: Windows CE USB Driver Tag: 76727

 - IR communication using non standard protocol Hi, I have an electronic device that communicates with my PC (running Windows XP) using infrared communication. The protocol it uses is like this: For instance to get a buffer status the PC can send B\r to the device, and the device will respond with something like B\r00\rOK\r if the buffer is empty. In other words you send the command to the device and it responds with the command, the answer to the request, and "OK". Currently I use an infrared transmitter connected to one of the COM ports in the PC to communicate with the device. In C sharp I have written a program that communicates directly with the COM port the device is connected to: I open the COM port, sends a command to the device, and waits for a response. It works okay but now I also want to use an IR transmitter connected to an USB port! Virtual com ports and IR is not a possible solution in Windows 2000/XP! Is there an IR communication class that makes it possible to write a program that uses the IR interface there is in Windows 2000/XP to communicate with any IR device - regardless of how it is connected to the PC (as long as it just has a driver)? I know there is something like this for (win)socket programming but will that be possible to use in this case/ with the protocol I described? Best regards, Kim Tag: Windows CE USB Driver Tag: 76722

During setup, after standard IRPs (i.e. start, hid_get_*, etc) minidriver receive a couple of IRP_MN_QUERY_ID ('BusRelations' and 'BusQueryHardwareIDs'), the number of collection it expose (in my case 4). Then it receive 2 IOCTL_HID_READ_REPORT for ping pong IRPs. At this time "new hardware" wizard ask me to click on "finish" button... So do I With Win2k, minidriver get 2 new IRP_MN_QUERY_ID and freeze. In device manager first collection appear this an exclamation mark. At this point I must reboot to unlock. Does something could be wrong in IRP_MN_QUERY_ID handling ? minidriver reply a string like "Vid_1234&Pid_5678" to those IRPs, is that correct ? Or there is something else to do ? note: in IOCTL_HID_READ_REPORT handler, I call IoMarkIrpPending() to the received IRPs and return STATUS_PENDING... Is that correct ?

 - Walter Oney WDM: CacheControlRequest() resets computer while calling IoMarkPending(Irp) Hi I'm using Walter Oney's book and routines to implement a driver for a PCI card. The code for CacheControlRequest() is exactly the same as on Walters Oney book on page 503 The computer resets completely while calling IoMarkPending(Irp) inside CacheControlRequest() While calling DispatchControl and IOCTL_WAIT_NOTIFY implemented without calling CacheControlRequest() the driver returns a Status value without problems. It is also possible without problems to call IOCTL_GET_VERSION_BUFFERED. Calling DispatchControl and IOCTL_WAIT_NOTIFY implemented with the CacheControlRequest() function resets the computer completely and later on starts without problems. What can be done to solve the problem? Any help or hints would be kindly apreciated Best Regards Tag: Windows CE USB Driver Tag: 76699

 - setting MTU size for NDISWAN I am trying to get a dialup connection to use 576 bytes MTU. I have tried setting the registry value that is supposed to do it ... HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\NdisWanIp\MTU but this does nothing at all! I have also tried setting this value ... HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MTU this also does nothing!!! Both times I restarted after making the change. My MTU size is always 1500!!! So now I'm trying to do it in my imdriver using OIDs ... OID_GEN_MAXIMUM_FRAME_SIZE and OID_WAN_SET_LINK_INFO ... guess what? These also do nothing!!! I am going to cry!!! Please can someone help?

 - Cancel a printer job Hi, I want to know if the following is possible. When an user tries to print a file, a dialog should pop up asking the user for his / her credentials. If the credentials are not correct then the print job for that file should be cancelled. I tried subscribing to the printer event e.g. JOB_CHANGED and then cancelled the print job. However, in many cases the file was already printed before my application could cancel the job. What is the right place to hook (e.g. Print monitor, Print provider, Print processor, Printer driver etc) into the printer to achieve the same. Thanks, Vishal Tag: Windows CE USB Driver Tag: 76663

 - Obtaining interrupt vector in IRP_MN_START_DEVICE Hello! I written a driver. It is a upper-filter driver for serial devices. The driver handles 4-byte timeout. Earlier, when I tested it in Intel under Windows XP SP1 it worked correctly, vector got by code if(PartialDescriptors[i].Type == CmResourceTypeInterrupt){ vector = stack->Parameters.StartDevice.AllocatedResourcesTranslated[0].List[0].PartialResourceList.PartialDescriptors[i].u.Interrupt.Vector; } has a correct value 0x34. Now I test driver in AMD under Windows XP SP2. Vector value is 0x191 - it is wrong, it is out of IDT bounds... What happens, explain me please. Tag: Windows CE USB Driver Tag: 76660

 - NDIS + Windows Mobile 5.0 = Fun? I've been thinking of getting a new PDA Phone. And then I got to thinking, hey if it uses the NDIS model I can probably hack it and do all sorts of funky stuff. Like make it a router (maybe) that my bluetooth enabled laptop could use, wirelessly, while I'm driving, and shaving, and drinking latte. So I started looking it up but I don't see any definitive answer on the driver model that Windows Mobile 5 uses. Can anyone help? Tag: Windows CE USB Driver Tag: 76652

 - Reading/Writing To A Device on SMBus in Windows XP Embedded I've seen several posting with answers related to this, but none with an answer so I want to try asking it a different way. I have a system running Windows XP Embedded. On it's SMBus there is a chip which controls the brightness and contrast of the LCD panel hooked into the LVDS. The problem is that the manufacturer of my board does not supply an API for my board to read and write to the SMBus. So, does anyone know what I have to do to be able to read and write (single bytes only) to this device on the SMBus? I have the SMBus Device Driver external architecture specification from Intel, but can't seem to get any of the examples in it to compile, despite hours of trying. I've also searched and searched for example or other information that would help but to no avail. My board has an Intel 82801DB/DBM SMBus Controller driver installed (hence why I was trying to use the specification from Intel, et al). Can anyone help me figure out what I'm doing wrong or where I can find information on reading from/writing to the SMBus? Thanks, Mike Tag: Windows CE USB Driver Tag: 76641

 - DMA mapping question Hello all, I am working on a driver for which I would like to DMA buffers to a device where the buffers have not been specifically allocated for a given device. These buffers are created common kernel memory and we don't know to which device they will be transmitted before hand. I would like to use MmAllocateContiguousMemory to get the buffers and MmGet PhysicalAddress to map them, but this MSDN is replete with warnings about using MmAllocateContiguousMemory for DMA. If we use AllocateCommonBuffer then we incur the cost of copying each buffer before transmission. Any suggestions on how we can effeciently DMA these buffers?

 - Newbie: How to create or allocate a copy of symbolic link (UNICODE_STRING)? : Hi all, I´m trying to get an inter-driver communication. I´d read that it´s better to make use of WorkItems instead of calling "IoGetDeviceObjectPointer" directly from the "IoRegisterPlugPlayNotification" callback function. (I´m using "IoRegisterInterface"). Ok. My problem is that I don´t know how to create or allocate a copy of the 'SymbolicLinkName' got from the 'IoRegisterPlugPlayNotification' notification structure. SymbolicLinkName is necessary because I need to call the "IoGetDeviceObjectPointer" function inside the "IoQueueWorkItem" callback routine. Here is my code: ------------------------------------------------------------ typedef struct _MY_WORK_CONTEXT { PIO_WORKITEM Item; PUNICODE_STRING SymbolicLinkName; } MY_WORK_CONTEXT, *PMY_WORK_CONTEXT; NTSTATUS PNPCallbackFunction( IN PDEVICE_INTERFACE_CHANGE_NOTIFICATION NotificationStructure, IN PVOID Context ) { NTSTATUS status = STATUS_SUCCESS; PDEVICE_INTERFACE_CHANGE_NOTIFICATION notify = NotificationStructure; PDEVICE_OBJECT deviceObject = (PDEVICE_OBJECT)Context; PIO_WORKITEM workItem; PMY_WORK_CONTEXT myWorkContext; if(IsEqualGUID(notify->Event, GUID_DEVICE_INTERFACE_ARRIVAL)) { workItem = IoAllocateWorkItem(deviceObject); myWorkContext = (PMY_WORK_CONTEXT) ExAllocatePoolWithTag(NonPagedPool, sizeof(MY_WORK_CONTEXT), 'cWbD'); if(!myWorkContext) { IoFreeWorkItem(workItem); return(STATUS_XXX); } // WorkItem to the CONTEXT struct myWorkContext->Item = workItem; // Symbolic Lynk to the CONTEXT struct myWorkContext->SymbolicLinkName = notify->SymbolicLinkName; // OF COURSE I CAN´T DO THAT... WHAT CAN I DO??? // Queue WorkItem IoQueueWorkItem(workItem, (PIO_WORKITEM_ROUTINE)CallbackWorker, DelayedWorkQueue, (PVOID)myWorkContext); } return status; } ---------------------------------------------------------------------- Can anybody help me? Thanks a lot!!! Paulo. Tag: Windows CE USB Driver Tag: 76627

 - How can I put dependency while installing a PNP driver? Hi All, I have two pci devices. Functional drivers for both these PNP devices need services from another driver(bus driver for a dummy device) which should be loaded first. If I try to install any PNP driver manually (from DeviceManager), how can the inf automatically install the non-PNP driver first ? I cannot load nonPNP driver as an export driver for some reason. StartType for nonPNP driver is SERVICE_BOOT_START and that for PNP drivers is SERVICE_DEMAND_START. I tried with Include and Needs on inf for PNP device to read inf for nonPNP device, but it installs only non-PNP driver and doesnot come back. So can any one suggest a solution for this? Thanks & Regards Biju Mohamed K Tag: Windows CE USB Driver Tag: 76626

 - When the spooler will go to RAW mode? Heya, since there is no way you can force some format over another, can the expected format to be "detected" in advance in order to warn the users or not list the printer or whatever... After some reading around I found out a nice list from Ashwin [MS] and completed by Carey Gregory: We'll go RAW in the following cases: - Printing to FILE: - this can be detected with ease - Printing directly to port (no spooling) - this can be detected with ease - Client disables "advanced printing features" in printer properties - How to detect this? Haven't seen a reference in all PRINTER_INFO structures or attribs? Additionally, for networking printing: - Client is anything other than NT/Win200/XP - Checking for a network port and then? - Client doesn't use a "true" connection - Don't even have an idea what that means, how to detect? - Printing to a "masq" printer (win9x, netware, etc.) - this one too... - Server has "printer attribute RAW only" bit set - this can be detected with ease - Server doesn't accept client's EMF version - how to detect? - Client and server OS versions don't match exactly - again, how to detect... Additionally, I have some network HP around - nice printer with a full cd drivers which take half an hour to install. Printing to it using its own drivers *always* result in RAW mode, while if I simply install HP LaserJet 6L and redirect it to the same IP, on the same PC, it goes to EMF. Something missing from the list? Tag: Windows CE USB Driver Tag: 76624
