I recently acquired a CanoScan LiDE 60. It basically works but it is very unstable: It often stops during the scan and sane returns an error, or it just hangs during the scan (making ugly noises). The only remedy is to re-plug the usb cable. (which sometimes causes a panic) I tried on my notebook which is running a recent current. It works flawlessly there - not a single error so far. So I upgraded my main computer to 6.1-PRERELEASE but the problem persists: - Are there any usb/ehci fixes in CURRENT that haven't made it to 6-stable yet? (I really don't want to update the machine that's making troubles to current) - Or is this more likely to be chipset related (the notebook dmesg shows <Intel 82801DB/L/M (ICH4) USB 2.0 controller> vs VIA on the computer that causes troubles) Also, it occured to me that this could be power related - the scanner doesn't require an external power suppply. I tried different USB ports but didn't notice any difference. dmesg can be found here: TIA, Stefan
