As far as I know the Adaptec parts can do multiple addreses, which is not part of umass specification. They may use a vendor extended umass or completely different protocol. Whatever it is - the device doesn't offer itself as beeing umass. With vendor specs it should be simple to teach our umass driver about this special device, even if it really isn't umass. Also firmware uploading in USB is very simple if you have vendor specs. Without specs all you can do is sniff Windows data and guess. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
