    - usb2.0 power management I am working with a usb2.0 composite device under winxp which has three interfaces printer,scanner and mass storage device. I have my own host2.0 stack and my composite driver takes care of the device. micrososft client drivers are loaded for the different functions(usbstor.sys,usbprint.sys and usbscan.sys). I have two problems during suspend/resume. 1. before initiating suspend, i access the mass storage device and leave the explorer associated with it open. after wake up i am able to still access the mass storage device, but i am not not able to access my printer. pls note that this problem does not happen when i close all the documents or the explorer from the mass storage device. 2. when i try to disconnect the device, my parent composite driver deletes all pdo and gets unloaded, when i connect the composite device again, windows says that " the previous instance of the mass storage driver is still in memory and so culdnt load the mass storage driver", in this case mass storage driver is never loaded unless i reboot the system. i strongly feel that the leaving the handles open from the mass stroage device has got some impact, becos i never encounter such problems when all the handles associated with the mass storage device is closed. any suggestion is appreciated, thanks Tag: FAT16 and FAT32 File system driver Tag: 39707

    - KERNEL_STACK_INPAGE_ERROR Hi, I have 1394 devie driver. I am writing async data of 10K each in loop. I got this problem. I didnot understand what caused the problem. Looking for suggestion on how to debug this problem. Sometime, I get DEVICE_IO_ERROR if the device otherside is in breakpoint or something like that. But I didnot understand why that caused BSOD. If the problem is in my driver, it doesnot say so. How can I further debug this. **************************************************************************** Use !analyze -v to get detailed debugging information. BugCheck 77, {c0000185, c0000185, 0, 4075000} Probably caused by : ntoskrnl.exe ( nt!MiMakeOutswappedPageResident+2b9 ) Followup: MachineOwner --------- kd> !nalyze -v No export nalyze found kd> !analyze -v ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* KERNEL_STACK_INPAGE_ERROR (77) The requested page of kernel data could not be read in.

An I/O status of c000009c (STATUS_DEVICE_DATA_ERROR) or C000016AL (STATUS_DISK_OPERATION_FAILED) normally indicates the data could not be read from the disk due to a bad block.

    - NDIS and IPv6 I've got an NDIS driver that does IPv4 packet filtering. If I try to use the same code to filter IPv6 packets, I don't see any reaching my driver. I don't see any updates in the DDK documentation for IPv6 - should I be seeing both v4 and v6 packets? Or is there an API change for this Thanks Chris B.

    - VaryingResourceMap and mf.sys problem I am writing an XP driver for a multiport serial PCI card. I am using mf.sys and VaryingResourceMap to split the card BAR0 memory range between the serial ports (memory mapped). I can see the ports enumerated in Device Manager as expected. However, when I get IRP_MN_START_DEVICE, the CmResourceTypeMemory resource in pIrpStack->Parameters.StartDevice.AllocatedResourcesTranslated-> List[0].PartialResourceList has u.Memory.Start identical for all (four) child devices. The Length member is 80, as expected. It looks like PnP manager (or mf.sys?) assigns all child devices the same memory range that is last 80 bytes of the PCI card memory range. The line in the inf file where I define the Varying Resource Map looks as follows: HKR,Child01,VaryingResourceMap,1,00, 00,01,00,00, 80,00,00,00 I understand that this means that I want memory on BAR0 at offset 0x100 bytes of length 0x80 bytes to be assigned to Child01. The full inf file is included at the end of this post. When I get IRP_MN_QUERY_RESOURCE_REQUIREMENTS I fill the memory resource requirement as follows: descriptor->Type = CmResourceTypeMemory; descriptor->ShareDisposition = CmResourceShareDeviceExclusive; descriptor->Flags = CM_RESOURCE_MEMORY_READ_WRITE; descriptor->u.Memory.Length = SERIAL_REGISTER_SPAN + SERIAL_STATUS_LENGTH; //7*0x10 + 1*0x10 descriptor->u.Memory.Alignment = 0x1; descriptor->u.Memory.MinimumAddress.QuadPart = 0; descriptor->u.Memory.MaximumAddress.QuadPart = 0xFFFFFFFFFFFFFFFF; I do not modify this memory requirement when I get IRP_MN_FILTER_RESOURCE_REQUIREMENTS. What can I be doing wrong? Any help is appreciated. Slawek Here is the full inf file: ; xrsio.inf ; ; Windows XP driver for MyCompany serial cards ; ; Copyright 2004, MyCompany, Inc.

    - generating low-level mouse messages MouseHead ========= Regarding www.spitbit.com/mousehead/index.htm web cam and voice activated hands-free mouse controller; even though MouseHead was an enormous amount of work, I am making it a no-cut-off freeware/tipware download, so please help. MouseHead works well on 160x120 video input feed at 10 fps, excellent at 20+ fps, with good pointer control, coverage and stability, primarily developed and tested at 1600x1200 desktop resolution (also works well on lower resolutions), low cpu utilization, about 3-12% on various test machines including Athlon1000, Laptop P3 650Mhz, P4 2.4GHz and Athlon2600. Given the following constraints: ===================== A) I don't have the Win DDK's except dating back many years to maybe MSDN WinNT 3.51 beta and before and have no money to pay for the current MSDN update. B) I want to support Win 9x/NT/2k/XP, preferably with one unified approach if possible. Two variations will be okay also. Specifically what I need is: ================== 1) Best approach to generate low kernel level mouse messages, because low level messages seems more of a natural fit, better than user level, and with the addition of mouse move message. 2) Best approach to display stable system-wide pointer. Currently using a transparent window with regions and a graphic painted on it. Please help. Thank you, Tim Reago Tag: FAT16 and FAT32 File system driver Tag: 39653

    - TURN $12 INTO $12,000 NOW!!! make extra cash GREAT WAY TO BECOME RICH...INSTANT THOUSANDS This is no scam, read it!!!!!! ------------------------------------------------------------------------ -------- HOW TO TURN $12 INTO $12,000!!!!!!!!!!!!!!!!!!!!!!!!!!!! THIS REALLY CAN MAKE YOU EASY MONEY!! IT WORKS !!! BUT YOU HAVE TO FOLLOW IT TO THE LETTER FOR IT TO WORK!!!! : A little while back, I was browsing through newsgroup, just like you are now and came across an article similar to this that said you could make thousands dollars within weeks with only an initial investment of $12.00! So I thought, "Yeah, right, this must be a scam", but like most of us, I was curious, so I kept reading. : Anyway, it said that you send $2.00 to each of the 6 names and address stated in the article. You then place your own name and address in the bottom of the list at #6, and post the article in at least 200 newsgroup. (There are thousands) No catch, that was it. So after thinking it over, and talking to few people first, I thought about trying it. I figured what have I got to lose except 6 stamps and $12.00, right? Like most of us I was a little skeptical and a little worried about the legal aspects of it : All, So I checked it out with the U.S. Post Office (1-800-725-2161) and they confirmed that it is indeed legal! Then I invested the measly $12.00. Well GUESS WHAT!!?. Within 7 days, I started getting money in the mail! I was shocked! I figured it would end soon, but the money just kept coming in. In my first week, I made about $25.00. By the end second week I had made a total over $1,000.00! In the third week I had over $10,000.00 and it's still growing. This is now my fourth week and I have made a total of just over $42,000.00 and it's still coming in rapidly. Its : Certainly worth $12.00, and 6 stamps, I have spent more than that on the lottery!! : Let me tell you how this works and most importantly, why it works?.also, make sure you print a copy of this article NOW, so you can get the information off of it as you need it. STEP 1: Get 6 separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 2 US $1.00 bills and place TWO inside EACH of the 6 pieces of paper so the bills will not be seen through the envelope to prevent thievery. Next, place one paper in each stating the above phrase, your name and address, and 2 $1.00 bills. What you are doing is creating a service by this. THIS IS ABSOLUTELY LEGAL! Mail the 6 envelopes to the following addresses: #1) Corteney Tomson P.O. Box 55 Dupo, IL 62239 #2) Brad Taylor 6 Terry Ln. Hutchinson, KS 67501 #3) Cedric Etienne 239 Autumn Breeze Way Winter Park, FL 32792 #4) Stephen Mitchell 1977 Alcovy Trace Way Lawrenceville, GA 30045 #5) Melissa Martinez 15440 sw 74 cir ct #607 Miami, FL 33193 #6) Maurice Sawyers 49 Middle Rose St Trenton, NJ 08618 STEP 2: Now take the #1 name off the list that you see above, move the other names up (6 becomes 5, 5 becomes 4, etc?.) and add YOUR Name as number 6 on the list. STEP 3: Change anything you need to, but try to keep this article as close to original as possible. Now, post your amended article to at least 200 newsgroups, message board. (I think there are close to 24,000 groups) All you need is 200, but remember, the more you post, the more money you make!---- DIRECTIONS----HOW TO POST TO NEWSGROUPS, MESSAGE BOARD----------Step 1) You do not need to re-type this entire letter to do your own posting. Simply put your cursor at the beginning of this letter and drag your : Cursor to the bottom of this document, and select 'copy' from the edit menu. This will copy the entire letter into the computer memory. Step 2) Open a blank 'notepad' file and place your cursor at the top of the blank page. From the 'edit' menu select 'paste'. This will paste a copy of the letter into notepad so that you can add your name to the list. Step 3) save your new notepad file as a .txt file. If you want to do your postings in different sittings, you'll always have this file to go back to. : Step 4) Use Netscape or Internet explorer and try searching for various newsgroups (on-line forums, message boards, chat sites, discussions.) Just example you log on any search engine like yahoo. com,google. com,altavista. com,excite. com then you search with this subject ? millionaire message board? or ?money making message board? or ? employment message board? or ?money making discussions? or ?money making forum? or ?business message board? etc. You will find thousand & thousand message board. Click one by one then you will find the option post a new message. : Step 5) Visit these message boards and post this article as a new message by highlighting the text of this letter and selecting paste from the edit menu. Fill in the Subject, this will be the header that everyone sees as they scroll through the list of postings in a particular group, click the post message button. You're done with your first one!. : Congratulations? THAT'S IT! All you have to do is jump to different newsgroups and post away, after you get the hang of it, and it will take about 30 seconds for each newsgroup! ** REMEMBER, THE MORE NEWSGROUPS OR MESSAGE BOARD YOU POST IN, THE MORE MONEY YOU EILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF 200** That's it! You will begin receiving money from around the world within days! You may eventually can rent a P.O. Box due to the large amount of mail you will receive. If you wish to stay anonymous, you can invent a name to use, as long as the postman will deliver it. **JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT. ** : Now the WHY part: Out of 200 postings, say I receive only 5 replies (a very low example). So then I Made $6.00 with my name at #6 on the letter. Now, each of the 5 persons who just sent me $2.00 make the MINIMUM 200 postings, each with my name at #5 and only 5 persons respond to each of the original 5, that is another $30.00 for me, now those 25 each make 200 MINIMUM posts with my name at #4 and only 5 replies each, I will bring in an additional:$150.00! Now, those 125 persons turn around and post the MINIMUM 200 with my name at #3 and only receive 5 replies each, I will make an additional $750.00! OK, now here is the fun part, each of those 625 persons post a MINIMUM 200 letters with my name at #2 and they only receive 5 replies, that just made me $3,750.00!!! Those 3,125 persons will all deliver this message to 200 newsgroups with my name at #1 and if still 5 persons per 200 newsgroups react I will receive $18,750.00! With an original investment of only $12.00! AMAZING! When your name is no longer on the list, you just take latest posting in the newsgroups, and send out another $12.00 to names on the list, putting your name at number 6 again. And start posting again. The thing to remember is, do you realize that thousands of people all over the world are joining the internet and reading these articles everyday, JUST LIKE YOU are now!! So can you afford $12.. and see if it really works?? I think so? People have said, 'what if the plan is played out and no one sends you: the money? So what are the chances of that happening when there are tons of new honest users and new honest people who are joining the internet and newsgroups everyday and are willing to give it a try? Estimates are at 20,000 to 50,000 new users, every day, with thousands of those joining the actual Internet. AND YES YOU HAVE TO SEND THE MONEY FOR THIS TO WORK!!!dont try not to,IT WONT WORK TRUST ME Tag: FAT16 and FAT32 File system driver Tag: 39649

    - How to handle system suspend when the device has been in selective suspend mode? To support selective suspend feature, the driver needs to submit an idle request Irp with IOCTL_INTERNAL_USB_SUBMIT_IDLE_NOTIFICATION device I/O control code. This idle request Irp will not be returned until it's cancelled or some other conditions. Currently, I never see the status is success when the complete routine is called. What kind of condition will cause the status is success? The complete routine will power on the device if the status is not success. If I try to suspend the system when the device has been in suspended mode , the idle request Irp is also cancelled. The complete routine try to power on the device since the status is not success. However, the system is currently trying to suspend. They will conflict!! If the complete routine power on the device before system suspend, it will be OK since the device will be power down again. However, if the complete power on the device after the system suspend, the system suspend will fail. I think the complete routine should not power on the device in this case. However, how do I know the idle request Irp is cancelled is due to system suspend? What should be the correct sequence for this condition??

    - how to detect the location on disk of a file when can't open it? Hi, We can find file LCN number by calling function FSCTL_GET_RETRIEVAL_POINTERS with a handle to the file, but there are some files can't open because it has already been opend by system, such as pagefile.sys, I know there is a tool(nfi.exe) can do it( It also failed if you just specified pagefile.sys, but will success if you dump all file info on disk. ) Does anyone know how to do? Thanks in advance! Polo Tag: FAT16 and FAT32 File system driver Tag: 39647

    - Driver Installer Hi, I have used this newsgroup so far and am able to do this, I have an inf to write an installer for a usb device, so I have SetupCopyInf to copy and update thed river into Windows. Now is there anything else that I can do to improve the user experience when they install our device. There are things like vid,pid, class of device that are mentioned in the newsgroup, but since I am new, I am not sure whether I have to use these or not. Now the way the installer or the four lines of code that I have written works is. 1.You run the installer first, after that when the device is connected, new hardware wizard pops up, you click next there, 2.On the next screen you select a driver from the list of drivers presented 3.Then click next and the driver is finally installed(i think ) and the device is ready to b used. Now I know since the driver is not signed, since its mentioned on the screen 2, maybe we have ge it signed. I have seen that for most installers the screen 1 or for that matter 2 never comes, you run the installer, you see a message that driver is not sined do you still want to install and then click yes there and after installation when device is connected, you dont again have to select the driver that you want to use for your device from a list of drivers available. So maybe I have to use some more functions to do that. All i need is some pointer / suggestion to which functions I can use and will look them up. Thanks a lot Shania Tag: FAT16 and FAT32 File system driver Tag: 39637

    - Reading Audio CD Text Data Anyone have an example of how to read cd text data? I am trying to use the IOCTL_CDROM_READ_TOC_EX command to return CDROM_TOC_CD_TEXT_DATA, but all I have been able to get is various errors: "The device is not ready" and "Incorrect Function" (each error with the same compiled exe but on different machines). Using the same drive handle and same audio CDs I have successfully read Track ISRCs and basic TOC info using IOCTL_CDROM_READ_Q_CHANNEL and IOCTL_CDROM_READ_TOC. What I do is I get a handle to my cd-rom, then I lock the cd-rom drive using IOCTL_CDROM_MEDIA_REMOVAL then I read the TOC from the cd using IOCTL_CDROM_READ_TOC then I loop through each of the songs from FirstTrack to LastTrack in the TOC and I get the ISRC using IOCTL_CDROM_READ_Q_CHANNEL and print it out and get the text data using IOCTL_CDROM_READ_TOC_EX and would print it out if it worked through each iteration. Then I unlock the cd drive. Below is the code I have in C++ that I am trying to use but getting the errors (DeviceIOControl returns FALSE and I get the text of the error with GetLastError()): hDevice is a a HANDLE to my cd rom drive retrieved with the CreateFile function. I know it is a valid handle because I can successfully open and close the cd drive and read the TOC (first & last track numbers and TRACK_DATA items) and read the track ISRCs. I am also curious if anyone knows how I can figure out the size I should specify of the output buffer for this command. Currently I am just setting it to 255 bytes, but don't know if that is enough or too much or what. BOOL getTrackTextData(HANDLE& hDevice, UCHAR trackNum, CDROM_TOC_CD_TEXT_DATA& output) { CDROM_READ_TOC_EX inBuf; inBuf.Format = CDROM_READ_TOC_EX_FORMAT_CDTEXT; inBuf.Reserved1 = 0; inBuf.Msf = 1; inBuf.SessionTrack = trackNum; inBuf.Reserved2 = 0; inBuf.Reserved3 = 0; BOOL bResult; DWORD bytesRet; bResult = DeviceIoControl(hDevice, IOCTL_CDROM_READ_TOC_EX, &inBuf, sizeof(inBuf), &output, 255, &bytesRet, (LPOVERLAPPED) NULL); if (bResult) { printf("Success with %i bytes returned.\n", bytesRet); } return (bResult); } the above function is then called with the following (where i is a loop counter and cdDevice is the cd-rom handle): .... CDROM_TOC_CD_TEXT_DATA trackCDText; bReturn = getTrackTextData(cdDevice, i, trackCDText); .... ps. sorry if this is not the best looking code, I am pretty new to c++ Thank You for any help you can provide.

    - SetPrinterData ERROR_ACCESS_DENIED Hi I am trying to install a windows printer driver uploaded on a RED-HAT 9.0 machine through a samba server. During Installation in the windows client, the setprinterdata function gets called to write the printer setting onto the registry. But here I get an access_denied error. But then I modified the code to open the registry manually and then write to the registry. This works fine. So I if I can still write to the registry using RegSetValue why does SetPrinterData give me Access_denied??? Please let me know if you guys ever had this problem and is there some fix to this behaviour of setprinterdata function. Thanks Debashis Tag: FAT16 and FAT32 File system driver Tag: 39619

    - Options for a NDIS-over-USB driver Hi, I am trying to figure out the best (i.e. easiest, fastest and least prone to error; yeah, I know) approach to developing a network driver for a USB-connected network card. From my research so far, I think I can do this in 3 different ways: 1. Remote NDIS - not really an option in this case because the network card has only 64Kbytes of RAM and most of it is used by the device firmware. 2. custom USB + NDIS driver - This seems to be the most complex option. I have written NDIS drivers before but have no experience writing a USB driver. 3. Use an NDIS-WDM driver - write an NDIS driver with a WDM lower edge. I am guessing that this will allow me to use the native USB driver leaving me to focus on the NDIS driver. Am I correct so far? Based on the above, (3) sounds the most promising way to go. If anyone has any other suggestions or comments, please let me know. Thanks, Harshal Tag: FAT16 and FAT32 File system driver Tag: 39616

    - Generating interrupts before my driver is loaded ? Hi All, I have a faulty PCI device which generates faulty interrupts. The device generates interrupts before my driver is loaded. This does not seem to bother WIndows NT 4.0 (probably it does not bother Win2K also). After my driver is loaded and I connect to the interrupt, it emmidiately calls my ISR routine and .... My questions are : *) How come it does not bother windows ? *) What does Windows do, with a PCI device generating an interrupt, before it's driver is loaded ? *) Does Windoes behaviour depend on the PC's HW (PIC/APIC) ? *) Does Windoes behaviour depend on the BUS causing the interrupt ? *) What will happen if the PCI device will cause a faulty interrupt after I Unload/Disable my driver ? *) Does Windoes behaviour depend on the whether or NOT this interrupt is shared ? *) Did Microsoft change it's behaviour between NT 4.0 to Win2k to WinXP ? *) What are the details of what Microsoft does when I connect/disconnect from an interrupt ?

    - Synchronization in filesystem drivers Hi, I am developing a filesystem filter driver, I have it to the point now where I am recording filesystem events by storing them in a queue, which is then processed (and emptied) by a system worker thread. Currently I am recording these events in the dispatch routine, to synchronize with the worker thread I am acquiring a spinlock (which the worker thread also has to acquire). So just a couple of basic questions: The dispatch routine will execute at PASSIVE_LEVEL, right? which means that using spinlocks is perhaps overkill? Can I use some other synchronization object, maybe mutexes, resources or critical sections? This would be better for me because then none of my code executes at DISPATCH_LEVEL whilst the lock is held, and I can work with pagable memory no problems. Assuming mutexes/whatever are OK, do I have any worries using them in a filesystem filter - are there any issues regarding blocking APC delivery - i.e. being alertable/not alertable?? Finally, what would the be the most appropriate sync object? I really can't decide between mutex/event/critical section etc.. Thanks, James Tag: FAT16 and FAT32 File system driver Tag: 39548

Buy the IFS kit
(http://www.microsoft.com/whdc/ddk/ifskit/default.mspx). You will
receive the FASTFAT (Windows NT FAT driver) sources.
