Xerox 4800 One Touch, also known as Xerox Onetouch 4800
USB
0x04a7
0x03a0
There are 4 SMD devices on the PCB:
L6219DS Motor driver
EliteMT M11B416256A 256Kx16 DRAM
a large QFP SMD with a heatsink, marked:
610800006021
0529-0601
FN8MK-000
a small QFTP SMD, marked:
61080001029 (possibly 4 zeros- very small print!)
0521MJT23
There is also a "Xerox One Touch 4800" which has a different product id. Looking at the picture, looks a lot like Visioneer OneTouch 9000 USB.
A USB trace is available.

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.
