Sorry for this, I didn't notice any issue here (aside for the chip working where it used not to). I have no idea what these zero-length packets correspond to, nor why they're affected by the transfer size. Do you have any idea what I should look for ? Because without that patch, the device is unusable for me :-/ Thanks! Willy
