I don't think the older drivers caught a SCSI bus reset (ENSCSIRST?) whereas the new driver does. These scanners seem to cause the controller to think the bus was reset (unless the scanners are actually resetting the bus!). A SCSI bus reset at device probe time gives the driver all sorts of problems. I don't know what causes the reset to occur, but take good look at the scanner, termination, and the cables.
