Implements the backend so that the generic driver can TX/RX to/from the USB device. TX is implemented with a kthread sitting in a never-ending loop that when kicked by the generic driver's TX code will pull data from the TX FIFO and send it to the device until it drains it. Then it goes back sleep, waiting for another kick. RX is implemented in a similar fashion, but reads are kicked in by the device notifying in the interrupt endpoint that data is ready. Device reset notifications are also sent via the notification endpoint. We need a thread contexts to run USB autopm functions (blocking) and to process the received data (can get to be heavy in processing time).
