This is needed for my G220F, otherwise it fails to initialize after the
existing firmware upload routine.

The vendor driver actually does more than what I have done here: it
downloads the firmware + boot code, modifies it, and uploads it again
(really messy). I have not copied that part over, as my device can get
on its feet without it.
