[Stephan M. <ste...@we...>]

This is most likely cause by the fact that you have installed
libusb's kernel driver as a filter. This doesn't work properly with
some HID devices.

Uninstall the filter and install the kernel driver as a normal device
driver through an .inf file (use inf-wizard.exe to create one).

It should work then.
