Drivers and inf’s do not consistently work and with so many versions of windows and hardware, I have battled issue after issue. I’m at the point now where I’m considering re-writing all my firmware, and all my drivers to use a hid device for windows driverless communication (already started).

Yes, exactly.

Use hider API, UsbDk_AddHideRule() etc.

I’ve posted patches to libusb-devel a few days ago. Please do not hesitate to send us problem reports if any.

You’re welcome!

P.S. While we are very interested to have people use and test UsbDk for different devices and in different scenarios, I must say that driverless HID device scheme is way better and simpler as long as your device functionally covered by HID specification, so maybe you should go that direction even if UsbDk works good for you...
