Check libusb is at least at version 1.0.8
Check libusb is at least at version 1.0.8

The driver will need to use libusb_exit() for libusbx >= 1.0.16 because
of the libusb hotplug thread.

libusb_exit() was not working correctly in libusb < 1.0.8.

So we check the libusb library used will at least provide a working
libusb_exit() function.
