It shouldn't be necessary to add the name of the backend. So if you use xsane and your scanner isn't listed, something is wrong. > I get: failed to open device - invalid argument Hm.

No need to connect, it's read automatically by the backend. > T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#= 4 Spd=12 MxCh= 0 > D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 > P: Vendor=04a9 ProdID=2204 Rev= 0.01 > S: Product=CanoScan FB630U > C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=500mA > I: If#= 0 Alt= 0 #EPs= 2 Cls=10(unk. ) Sub=01 Prot=00 Driver=(none) > E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms > E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms That's your scanner.

This is not your canon630u.conf. At least not the one you used when running scanimage -L. Did you compile sane 1.0.9 yourself? Then the config files are in /usr/local/etc/sane.d/ . Don't touch the config file, the original one is correct and works, as you've seen by scanimage -L. "device" is not allowed in canon630u.conf. If you really want to add device names, just do so without "device". See the examples at the end of the file. But you don't need that. I guess the real issue is that xsane doesn't work but scanimage does. If you don't have two SANE installations, the only reason I can think of are permission problems. E.g. if you run scanimage as root and xsane as user. See man sane-usb for some hints about this. Bye, Henning
