Probably SCSI over USB. After opening these inscriptions are visible:
CARD Z919-03 Main Other references found : YH1-0776 YG7-0139-03 [25G] The biggest chipset is (more than 200 pins) : Canon Kikka YH4-0201 0214 Z24 Another one : Malaysia 29F400TC-90PFTN 0208F59S The next one : 0212EAI TMP95C265F F0025ZAE Japan Again : RONALDO # nice name...:-) FH4-6069 T6W93B-0002 Japan 0206EAI D0078AAA And the last one : LSI LSA0002 CF92A Y0204 WPE04020 *or* WPD4020 (not sure)
Dave Burns is trying to write a backend for that scanner.
Eric Bachard is interested in
getting this scanner supported. He provides more details about it in
to sane-devel on 2003-08-07 and yet more information in this
Ulrich Deiters ukd at xenon.pc.Uni-Koeln.DE writes: I had a look at a transaction log of a Canon FS4000 connected via SCSI: The SCSI commands are not the same as for the other Canon scanners. A number of them is vendor-specific and - since Canon does not make programming details available - undocumented. Hence the Canon-SCSI backend cannot be used for this scanner.
The /proc/bus/usb/devices output looks similar to the Canon FB620.
Is reported to work with Vuescan (SCSI).

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.
