Could somebody post the winusb.inf file from Windows 8 please? I am studying the WCID technology and would like to take a look at the file. Unfortunately, I do not have any machine running Windows 8 around at the moment. Thanks in advance!

Tsuneo, thanks a lot!! I am failing to download the ISO file off Microsoft site for some reason... That's exactly the page I was looking at writing the first post here :) I've tried the descriptors and it seems to work fine with Windows XP SP3 and Windows 7 machines I have around. Zadig is a very handy utility too. Here is a link to some interesting rant on Microsoft, Microchip and WCID http://comments.gmane.org...sb.devel.general/16783

Tsuneo, could you please check the registry for the WinUsb class in Windows 8 as well? The class GUID is {88BAE032-5A81-49f0-BC3D-A4FF138216D6}. If you do a search for the GUID, you will find it easily. If you could export it to a file and post please, I would appreciate it very much.

Here is what I could see with Windows XP and a custom WCID device. It is possible to have a generic INF-file with USB\MS_COMP_WINUSB instead of VID-PID pair. XP recognizes a WCID device and accepts this kind of INF that installs WinUSB as the functional driver. See the ZIP attached. I did not include heavy DLL files. You will need to replace them with real binaries from the latest WDK. It seems it is the only advantage WCID have with XP, i.e. the generic INF. XP will ask for the driver once again if another WCID device is found, i.e. VID/PID is different. Otherwise, WinUSB seems to work fine for this kind of driver installation.
