I'm new to Ubuntu, so haven't tried using my LIDE50 with any release prior to Karmic. I have similar results to jhoyne, with additional error text:
sane-find-scanner output: found USB scanner (vendor=0x04a9 [Canon], product=0x2213 [CanoScan], chip=GL841) at libusb:001:007 scanimage -L output: WARNING: Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect device `genesys:libusb:001:007' is a Canon LiDE 35/40/50 flatbed scanner A couple of things I've tried without success: 1) I read that there may be a problem with Karmic suspending USB to save power; the suggested fix was to install scanbuttond to provide regular 'keep alive' activity and prevent the USB from being suspended. Installed and run, no difference. 2) I've seen several suggestions relating to the mode assigned to the device in config files; the common theme seems to be to replace mode=664 with mode=0666 to allow the device to be run by non-root users. The file most often suggested is /etc/udev/rules.d/45-libsane.rules which doesn't (or didn't) exist. I found a link to a copy of this file at http://forums.linuxmint.com/viewtopic.php?f=49&t=5945 Installed it, edited the entry for the LIDE 50 to show mode=0666, and rebooted. No change. I also found a similar reference to another config file /lib/udev/rules.d/50-udev-default.rules where I changed the mode of the USB subsystem to '0666' at point # libusb device nodes. No change. I also tried running xsane as root just to rule out any permissions problems. Failed with the same error. Finally, I found a hint at how to get a debug file from Xsane and ran the following: SANE_DEBUG_GENESYS=255 xsane 2>lide50.log which generated the following error info at a point within the log file: [genesys] sanei_genesys_read_data_from_scanner: timeout, buffer does not get filled [genesys] genesys_flatbed_calibration: offset calibration failed: Error during device I/O [genesys] genesys_start_scan: failed to do flatbed calibration: Error during device I/O I guess that it just doesn't want to work! Any ideas?
