If you install the scsitools package, it comes with a tool called<br>
rescan-scsi-bus.sh that will (at least in theory) let you do exactly this.<=

<br>
I'm assuming you don't need to scan LUNs or channels, just devices,=
so<br>
something like:<br>
<br>
rescan-scsi-bus.sh -r<br>
<br>
before you connect the scanner, and again when you unplug it and are done<b=
r>
with it, should do the trick. If it doesn't, throw an extra "-w=
" option on<br>
there and try again.<br>
