Canon DR-7580
USB / SCSI
0x04a9
0x160b
unknown
The Canon DR-7580 and DR-9080c are essentially the same scanner. The difference is that the 7580 is B&W and the 9080c is color. This is generally driven by "ISIS" (Pixtran / Captiva ) drivers in Windows and is a high-speed document imaging scanner. Captiva was at first hopeful they could help with a Linux solution but finally stopped returning my calls.

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.
