Hi, I have exactly the same problem as described by Harald Judt in this mail: http://www.spinics.net/lists/linux-usb/msg58841.html The thread ends here, in mid conversation with Sarah Sharp: http://www.spinics.net/lists/linux-usb/msg69636.html ... so I'd like to take it up from there. The scanner is a Canoscan N670U (LiDE 20). sane-fine-scanner finds the scanner: found USB scanner (vendor=0x04a9 [Canon], product=0x220d [CanoScan]) at libusb:003:003 but scanimage -L fails (no output) The attached (3.9.2) kernel log is from boot, to supply all usb initialisation messages. Around 46.650933 I did the sane-find-scanner. Starting 60.438552 you see output of scanimage -L and 707.400622 again so it's isolated from possible noise. The scanner is fully functional on my old laptop with USB2 ports. Hope this helps resolving the bug. Best regards, Martin van Es -- If 'but' was any useful, it would be a logic operator
