Hi list, (please CC me, as I am not subscribed, thanks!)
could anybody with more clue than me *please* help me debug my issues with a Canon n1220u ?? (with sane-backends-1.0.15 on vanilla 2.6.12) Short version: $ scanimage -L plustek:libusb:002:040' is a Canon N1220U USB flatbed scanner $ scanimage -T scanimage: sane_start: Error during device I/O Debug output follows at the end of this mail. I seem to have some UIO errors and finally usbDev_open() fails. So this might be a libusb problem, but I tried different versions, 0.1.10a and 0.1.8 both show the same behaviour. Any hints how to get more info about what exactly goes wrong here are highly appreciated!! Cheers, Mathis $ scanimage -L ...
