I don't know how much CPM1 differs from CPM2, but there was
somewhat successfull attempt to add CPM2 USB support to FHCI
driver (so far it supports only QE/"CPM3" USB), made by Laurent
Pinchart. I don't quite remember if he posted the patch to some
mailinglist, but I have the patch in my mailbox.

I can post it somewhere if Laurent don't mind. Cc'ing...
