[sane-devel] PIXMA TS8300 Series not working

Hi,
I've uninstalled ippusbxd, then reboot... and as a result the scanner is
not detected anymore!
'scanimage -L' returns "No scanners were identified."
'sane-find-scanner' still lists the scanner among the USB devices
(output of 'sudo sane-find-scanner -v -v' is attached).
I don't understand you point regarding the scanner being plugged in USB.
Do you mean it would better to have it connected through Wifi ?
Regards,
Yoann

# sane-find-scanner will now attempt to detect your scanner. If the
