Public bug reported:
I've an agfa snapscan 310 scsi connected to de back of an Epson Filmscan 200.
The Epson Filmscan 200 is connected on a scsi card.
Both scanners are recognized on win xp and on linux mandrake 9.2 in
vuescan 8.4.31...
In Ubuntu feisty Fawn 2.6.20-16-generic (under Gnome), it appears that
the devices are changing in "/dev/sg*"
After a reboot, only the Agfa is recognized but if I change an other
"sg*" other than the "sg*" of the scanner Agfa or of the cdrom, and I put it in
scanner group, both scanners are recognized for this session if I restart
vuescan 8.4.31...
The problem is that what is modified in "/dev/sg*" in a ubuntu session
for the Epson is changed when I reboot the system and then, the Epson will not
be recognized.
For example, after reboot the followings commands give this:

Only the Agfa is recognized by this way in sg4.
I close vuescan and I do:
[EMAIL PROTECTED]:~$ sudo gnome-commander
I go to /dev/sg5 ==>Properties ==> Autorisations ==> and I change the
group from root to scanner.
Then restart vuescan and both scanners are recognized!!!
I shutdown the computer, power on for both scanners before; power on
for the computer, starting ubuntu and:

Only one scanner (Agfa) and not on the same place as before...
I go to /dev/sg1 ==>Properties ==> Autorisations ==> and I change the
group from root to scanner.
Then restart vuescan and both scanners are recognized!!!

Have you an idea to fix it?
Thanks for reply.
