Looks like another device based on the broken scanlogic chipset. The later ScanLogic chips works just fine, but there are devices out there that still use the broken ones.
Go in linux/drivers/usb/storage/transport.c, into the function Bulk_transport(). Look for an if() clause that tests Tag == Tag, and remove just that test from the if(), leaving everything else in place. Recompile, and it _should_ work.
