No. You can probe for devices while Linux is running. Just issue the
following command as root:
echo "scsi add-single-device 0 0 4 0" > /proc/scsi/scsi
... that's for my system, where the scanner is attached as device number
four on the first adapter. Just replace the "4" with the ID of your
scanner.
If you want to power down the scanner without rebooting you have to
remove the scanner first from the SCSI system by using the following
command (again, this is for device number four, just use your ID):
echo "scsi remove-single-device 0 0 4 0" > /proc/scsi/scsi

Again, this is not necessary: Let's assume, that your scanner is
connected as device number four, therefore it will show up as
/dev/sg4. The file mode on this device is what lets you scan, or
what gives you the error message when xscanimage is not setuid root.
So if you create a new group "scan" and make yourself a member of this
group and set the group of the /dev/sg4 device file to "scan", and
set the file mode to 660 you can scan without having xscanimage be
setuid root.
BTW: Check out xsane, which is a much better frontend than xscanimage.
You can find it at http://www.wolfsburg.de/~rauch/sane/sane-xsane.html
Your scanner is not used with all it's capabilities if you are using
Sane "out of the box". There is a better backend available from
Christian Bucher at http://www.vernetzt.at/~bucher/Epson/Epson.html
Read the installation instructions and if you have any questions
regarding the installation, ask me. Don't bother Christian too much
so that he can use his time for making his software even better :-)
Have fun scanning,
Karl Heinz
