Hello, Sorry.

I just did a perfect scan with this scanner, as root. All I made is removing the 
plustek.conf (renaming to plustek.conf.tmp). As root, xscanimage works 
perfectly. 

I just have now to solve the problem of the root user. My device has the group 
'scanner' : 

/dev/bus/usb/003:
total 0
crw-rw-r-- 1 root root    189, 256 27 sept. 10:29 001
crw-rw-r-- 1 root scanner 189, 261 27 sept. 10:35 006
crw-rw-r-- 1 root root    189, 262 27 sept. 10:26 007

I'm in the scanner group but I am unable to access the scanner through scanimage 
or xsane as a normal user. Someone could help ? 

Thank you.
