Hi all,

I've been wrestling with this for a little while.  I can't seem to get
scanimage to recognize my CanoScan N656U.  It's a USB scanner supported by
the plustek backend.  So far I have done:

modprobe scanner vendor=0x04a9 product=0x2206

Which gives me the /dev/usb/scanner0 device (permissions crw-rw-rw) with
links from /dev/usbscanner and /dev/usbscanner0.  USB Viewer returns:

                        Max Packet Size: 64
                        Interval: 0ms

I've updated the /etc/sane.d/plustek.conf file to:

[usb] 0x04a9 0x2206
option lampOff 0
option warmup 180
option lOffOnEnd 0
device /dev/usb/scanner0

And sane-find-scanner gives back:

sane-find-scanner: found USB scanner (vendor = 0x04a9, product = 0x2206)
at device /dev/usb/scanner0
sane-find-scanner: found USB scanner (vendor = 0x04a9, product = 0x2206)
at device /dev/usbscanner
sane-find-scanner: found USB scanner (vendor = 0x04a9, product = 0x2206)
at device /dev/usbscanner0

And yet scanimage on maximum debug returns (pertinent part only):

[plustek] attach (/dev/usb/scanner0, 0xbfffd7fc, (nil))
[plustek] Device configuration:
[plustek] device name  : >/dev/usb/scanner0<

Anyone have any idea what I've done wrong/have yet to do?

Thanks!
