Apparently failing on first usb write attempt, so something wrong with libusb or low level usb communication (this portion of code is common to all PIXMA devices).
Could you add all usb logs : $ export SANE_DEBUG_SANEI_USB=255 $ export SANE_DEBUG=255 $ export SANE_DEBUG_PIXMA=21 $ scanimage -T 2> /tmp/logfile Zip and send back the /tmp/logfile Nicolas Wade Fitzpatrick-2 wrote: > > Thanks for the responses.
