A few questions.
1) What is the OS version?

2) How do you automatically install WinUSB driver by Windows OS?
If you use the Windows OS Descriptor, please check the following. You
can post the whole USB Descriptor of your device.

3) As the above website suggests, you can download libusb-1.0 Windows
binary and use xusb to test your WCID device.
