WinUSB on XP without WDK
in [Device Drivers]
|
From: giajh01 on 29 Oct 2009 18:22 Hi, warning. newbie question follows! I'm trying to use WinUSB (WDK 7) on XP with SP2. After a wee bit of work finally got the INF file to recognise and install the WinUSB and KMDF drivers when the device is connected. Everything works beautifully, my small test app communicates (via WinUSB) with my target hardware. So feeling dead chuffed with myself I asked my college to try out my new driver package (INF + coinstallers). And that's where it all went sour! His system is also XP SP2 but without WDK (shouldn't be necessary right). Driver install works fine, but when he fires up the test application it hangs on the 1st WinUSB_WritePipe call. After trying various things (examing installed driver, log files, registery, rebooting etc.) we install WDK on his system, and low and behold everything works suddenly. Now obviously, I've missed something, but I'm dammed if I can spot it. Anyone here come across a similar issue, or are the symtoms ringing any bells for anyone? Also, on a side issue, how can I find the control GUID for WinUSB to use tracelog to dig a bit deeper into what's happening when the WinUSB call hangs? thanks in advance
From: Doron Holan [MSFT] on 29 Oct 2009 19:09 are you installing with the winusb and kmdf v1.9 coinstallers? if you get as far as opening a winusb handle, there should be no need for any more wdk components, a hang in winusb_writepipe is indicative of a bug in your app or the hw is hung d -- This posting is provided "AS IS" with no warranties, and confers no rights.

From: giajh01 on 1 Nov 2009 14:31 yes I'm using the v1.9 CoInstallers. Not sure I follow why, a libaray call hanging is necessarily a bug in the application making the call. Just for clarification, the exact same app and HW works fine on my own PC. I've since had a chance to test this on 2 other PCs (one incidently only supporting USB1.1) and on both those systems the test application runs fine. Obviously there's something dodgy on my the single PC, but God knows what it is. I guess I could try persuading my collegue to uninstall WDK and see if the problem reappears but to be honest I don't fancy my chances of either a) him agreeing b) the problem reappearing "Doron Holan [MSFT]" wrote: > are you installing with the winusb and kmdf v1.9 coinstallers? if you get > as far as opening a winusb handle, there should be no need for any more wdk > components, a hang in winusb_writepipe is indicative of a bug in your app or > the hw is hung > > d > > -- > > This posting is provided "AS IS" with no warranties, and confers no rights. > > > "giajh01" <giajh01(a)discussions.microsoft.com> wrote in message > news:5D6AECC3-6631-4E1A-B24A-7D5EA65664A1(a)microsoft.com... > > Hi, > > > > warning. newbie question follows! > > > > I'm trying to use WinUSB (WDK 7) on XP with SP2.

From: Doron Holan [MSFT] on 3 Nov 2009 14:06 you need to attach a debugger (windbg) and see exactly where the call is hanging d "giajh01" <giajh01(a)discussions.microsoft.com> wrote in message news:0C295F9C-387B-4E87-B1FE-0908321E5B18(a)microsoft.com... > yes I'm using the v1.9 CoInstallers. > > Not sure I follow why, a libaray call hanging is necessarily a bug in the > application > making the call.

From: giajh01 on 3 Dec 2009 14:43 Hi, sorry for not getting back on this sooner. As expected the enthusiasm level for uninstalling WDK was low. It did however transpire that my collegue had similar/worse issues (BSOD even) with a USB->Com adaptor on the same PC. In short appears to be a HW issue there. If I discover anymore I'll post it here "Doron Holan [MSFT]" wrote: > you need to attach a debugger (windbg) and see exactly where the call is > hanging > > d >
