I have about 200 line of code not posted in this first release that can
increse performance and fix some potential leak. I prefer to wait a

i have 3 different devices, a vibook an hp docking station and an asus

yes, this is why later in the code you find 2 urb allocation, the
original module reuse the same 2 urb for bulk e control messages.
