I was just mucking around with a 100MB USB Zip myself and asking similar questions... > Dan Nelson writes: > > You have a couple choices for a) > > 1. wire down your devices in your kernel config so each physical device > (bus 1, id 1, lun 0) always appears as the same logical device (da0, > etc). see LINT for examples. I've checked the LINT file and it explained this as though I have a SCSI controller installed. What if the USB zip drive is used in a machine that doesn't have a SCSI controller? Same LINT code apply? I'd don't want to plug/unplug everytime the machine boots/reboots..Is this possible? > 2. shuffle the SCSI IDs so your ZIP has a higher ID ??? I'm not sure, but I don't believe my USB zip has a SCSI ID switch/shunt/jumper/etc...Sorry if this sounds silly, but what exactly do you mean here? What kernel config args are you suggesting? > 3. edit /etc/fstab and change the mountpoints to reflect the fact that > your drives have moved. > > for b), make sure your scsi bus is idle, plug ZIP thing in and run > "camcontrol rescan".
