fzago at austin rr com writes about the Memorex 6142u: Rebadged primax. Chipset: Primax E5. Also same as Visionneer Onetouch 4400. Hacking the viceo backend got me some results (head moving).
USB Descriptor looks similar to Genius Colorpage Vivid III (USB) and Pacific Image Electronics (PIE) Primefilm 1800u .

# Want to add or correct information?

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.

# Information for Manufacturers

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.
