[sane-devel] MacOS X 10.2.6 CanoScan N650U

[Bill Clyde]

I am trying to get my N650U to work through the USB port. scanimage -L 
does not see any scanners.

sane-find-scanner outputs:
found USB scanner (vendor=0x04a9 [Canon], product=0x2206 [CanoScan]) at 
libusb:-07:006.

I checked through the list archive and found $ SANE_DEBUG_SANEI_USB=5 
scanimage -L.

This outputs:

I also tried this:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
[dll] sane_exit: exiting
[dll] sane_exit: calling backend `plustek's exit function
[dll] sane_exit: finished

The plustek.conf file contains
[usb] 0x04A9 0x2206
device auto

I also tried specifying the device in the config file and on the 
command line but to no avail.

Let me know if there is anything else that I can look at to help 
resolve this.

Thanks,
Bill
