Canon Canoscan D646U
Canon Canoscan D646U ex
USB
0x04a9
0x220b
Maybe Genesys USB bridge + LM9830?
There is a test program at sourceforge. Get the
source from cvs (module canon, file ct_D646U.c).
Maybe could be
supported by canon630u backend?

If anything is wrong or missing on this page please file a bug report or use the the form for adding an unsupported device.
If you own an unsupported scanner, please send as much information as possible. Especially the output of sane-find-scanner -v -v and/or cat /proc/scsi/scsi (for SCSI scanners) or cat /proc/bus/usb/devices (for USB scanners) can help. If you dare to open the scanner, have a look at the text that's printed on the chips. That may help to identify the chipset. If you know that the scanner is similar to another one (e.g. supported by the same Windows driver), please also mention this fact.
Are you a manufacturer or vendor of scanners and one of your scanners is not supported by SANE yet? In this case please have a look at our information for manufacturers.
