I turn my Umax scanner off and on while the computer is running, and
haven't had any problems. No promises, of course.
You can tell Linux to re-probe for a device at a specific location by
echoing something to /proc/scsi/scsi -- here's a snip from
/usr/src/linux/drivers/scsi/scsi.c:
* Usage: echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi
* with "0 1 2 3" replaced by your "Host Channel Id Lun".
* Consider this feature BETA.
* CAUTION: This is not for hotplugging your peripherals. As
* SCSI was not designed for this you could damage your
* hardware !
* However perhaps it is legal to switch on an
* already connected device. It is perhaps not
* guaranteed this device doesn't corrupt an ongoing data transfer.
You should only need to do this if the scanner wasn't on (or ready)
when you booted.
