This is slightly off-topic, as I suspect the problem is entirely in hardware, but there's a lot of good knowledge on this list, so:
I have a BusLogic (now Mylex) BT958 that works very well. I've got a Zip and two ultra SCSI-II drives on the internal 50-pin cable. They work great. Recently I've acquired a UMAX Astra 1200S (DB25- SCSI-II) that I'd like to use with SANE, through the BusLogic host. I bought a cable that will attach to the scanner (DB25) and the host (72-pin SCSI-III UW). The scanner is the only external device. When the hard drives are not on the internal bus, *or* when they are set to "Asynchronous" in the AutoSCSI firmware, the bus will scan and detect the scanner fine. The hard drives will be detected too, but they don't actually work when set to "Asynchronous." When the hard drives are connected and set to "Sync 10mb/s" as they should be, a bus scan stops (locks up) when it reaches the SCSI ID of one of the hard drives. Of course, if the scanner is not connected at all everything is fine. Interestingly, if the scanner is not connected to the other end of the new external cable, but the cable *is* connected to the external BusLogic port, the same problems arise that I described in the last paragraph. So: Is the cable bad? Is it impossible to run a DB25 SCSI-II device on a 68-pin SCSI-III f/w port? *Or* should it be possible to configure the BusLogic kernel driver to allow my hard drives to be accessed in "Asynchronous" mode? Any thoughts? TIA, Jesse -- Jesse Jacobsen <[EMAIL PROTECTED]> PGP public key at http://www.jvlnet.com/~jjacobsen/pgpkey.asc or through the keyserver at keys.pgp.net.
