1) You should use asynchronous libusb API. Using synchronous API is
not acceptable.
2) Please try to avoid using libusb_device_reset(). Find out how
Windows driver deinitializes the device
3) Move functions from header into *c file

4) Last but not least - you have to prepare proper git-formatted
patch. Clone libfprint git repo instead of creating new one, add your
changes, commit, push to github.

Vasily
