Message:

Add simple USB multi interface device driver

The MID driver serves as a mini bus driver for devices with several
interfaces or for devices with classes defined at interface level.

The keyboard driver is working with this driver with the same problems
as before introduction of USB MID driver.

The merge also includes addition of bulk transfers.
