PyUSB

[joeadam]

Great library!

For me to get it to work I had to change the order of imports in __init (https://github.com/drbild/cp2130/blob/master/cp2130/__init__.py#32) as the usb import did not raise an exception, but it then failed with LIBUSB_ERROR_NOT_SUPPORTED [-12] error. However import pyusb first worked well

I also had to remove the call to is_kernel_driver_active in https://github.com/drbild/cp2130/blob/master/cp2130/usb/pyusb.py as it was marked as NotImplemented.

I have pyusb 1.2.1 installed. (import usb, usn._version.version)
