This is a major work item but we should try to rebase of Bitcraze latest firmware.

We need to reproduce the logic for the usb driver found here: https://raw.githubusercontent.com/bitcraze/crazyflie-clients-python/develop/lib/cflib/drivers/crazyradio.py It created the problem that is discussed here (with a temporary fix): https://github.com/blandry/crazyflie-tools/issues/21#issuecomment-120319627

We need to setup better documentation for installation and usage.
