Just to add to question #2 above:
The problem computer is running Windows 7 64-bit SP1 (Build 7601). I have tried changing the USB product id to something new, but that also does not seem to solve the problem for me. No matter what I do, the inbox WinUSB drivers plus this winusbcompat.inf file do not register the DeviceInterfaceGUID on this one specific computer. Are there any WinUSB registry settings I could check?
