Is reported to use a Genesys Logic GL660USB chip (USB 2.0 converter) and the Avision B2 (=GL646) chipset.
Main circuit board: AVISION B2 \ 163-54-001005 \ 0215E38B3
GL660USB \ 0221MF3K7-32 \ 164-07-000660
tm TECH 0041 \ 100 MHz \ NA010MN T224162B-25J
Aux. circuit board: L6219DS \ 6992D0215 \ ST Malaysia
F P22SD \ 7 4VHCUO4
Will most probably work with the Genesys backend, when it's finished.

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.
