Sorry for not commenting on many things on this list. I am too busy to check all this. Perhaps my USB code might help in some occasions for scsi.c, I am not completely sure if they are in sync. I sent in the USB code earlier. This code can be committed, although endianess is not handled correctly at all places. -- Marco
