I recompiled sane-backends and linked it against libusb20. The include path
needed to be fixed.
scanimage -L doesn't detect any scanners.
sane-find-scanner correctly detects it on first run:
found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan],
chip=GL842) at libusb:/dev/usb:/dev/ugen3.2
on subsequent runs no scanners are found
dmesg only says
ugen3.2: <Canon> at usbus3
no ugen detached message even if I unplug the scanner
I tried some of the debugging sysctls but I couldn't spot anything useful.
ugen seems to work in general as I could access my camera with libgphoto2.
Will provide more info as needed.
