I use the MX28, so I made these two patches (follow). I'll roll them into an
official thingie and submit properly, but I'd like to know Greg's opinion first.
First patch is the obvious increment, but I also need the second one which adds
quirk for the MX28 bootrom. If you issue such command to it, the bootrom
crashes, therefore the quirk.
With these in place, I can get some output from the bootrom finally using
libusb.
Greg, can you please take an experienced look on these (and avoid tearing me
limb to limb because I didn't submit them properly ;-) ) and tell me your
opinion?
Thanks!
