Michal: I just came across a bug in the net2280 driver. A quick check shows it's present in many of the other UDC drivers as well. The bug is related to the switch from usb_gadget_driver:speed to max_speed, and it's also related to the increasing support for USB_SPEED_SUPER. In Felipe's tree, net2280_start() has code like this: if (!driver || driver->max_speed != USB_SPEED_HIGH || !driver->setup) return -EINVAL; The test should be: driver->max_speed < USB_SPEED_HIGH. As it is, the UDC driver won't accept gadget drivers that support SuperSpeed. A similar problem is present in Greg's tree, but fixing it there will be more difficult. The easiest approach might be to get commit d93bb846f5 (usb: gadget: rename usb_gadget_driver::speed to max_speed) into Greg's tree and then add a fix on top of it. What do you think?
