USB
0x04a7
0x0410
      Plustek ASIC P99002A
 ALI Jpeg/USB M5615
 Uses a winbond
      microcontroller; there are separate RAM chips for the JPEG and controller,
      and an external +socketed rom for the controller.
    
The 8820 is the same as the 8800 but has an additional transparency adapter.

    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.
