Try the patch below. If it still doesn't work, give the kernel message again and lsusb -v output, too.
Did it make any difference?
No, it unfortunately did not.
lsusb is attached and the parts of the kernel log are in the mail:

Hm, it looks better than before (it was '3:-1:3' or such), but there is still something strange there.
Sorry for the long delay on this. I finally found some time to look into this and it seems that I got the calls to usb_set_interface wrong. Attached is a patch to fix this - could everybody who is affect please give that a quick try? More explanation is in the commit log.
Thanks, Daniel
