 could you please try the first patch and see if that lets you use your device
 without any manual quirks?
 if that works it would be nice if you could also try the second patch. maybe
 the existing scsi quirks aren't necessary anymore. this is just a guess
 however. if your device stops working after you've applied the second patch,
 please revert it and only use the first patch.
