I think it is better that you start a new thread since your subject is
different from the thread. So please do that next time.

What do you mean by winusb.sys can not start? What it the error
code? Is it code 10 error? Are you using XP or Vista or Win7?
32bit or 64bit?

If the driver is not installed properly, then you cann't open the device by
calling libusb_open_device_with_VID_PID.
