The result remains the same to not import libusb01.
How can I test that there is data really staying in EP6 ?
>>> from usb.backend import libusb01
>>> b = libusb01.get_backend()
>>> dev = usb.core.find(idVendor=0x0547, idProduct=0x1002, backend = b)
>>> dev.set_configuration()
>>> ret = dev.read(0x86, 1024, 0, 100)
Traceback (most recent call last):

File "/usr/lib/python2.7/site-packages/usb/core.py", line 624, in read

Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
