With the current version of libusb 0.1x, I believe you won't be able to
achieve what you want to do. since you can not really use the filter
driver with  HID device. Somewhere I read that the filter driver will not be
actively supported but I can not find the reference now.

You can do this in Windows without using libusb (using Raw Input).

The new development version (1.x) will support HID as a backend.
I can find the HID device with the new HID backend. However,
read and write are not working yet.
