USB

## Vendor ID

0x08f0

## Product ID

0x0004

## Chipset

SL1148C

## Comments

Hardware is from SYScan, but with modifications. I (rbackes bond de) have pictures of the circuit board available. I suppose the main Chip is a SL1148c, seens to be from CYPRESS Semiconductor.'

# 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.
