Hi all,
I've been looking at the list of unsupported Canon scanners,
concentrating on the CanoScan and LiDE series. Seems the LiDE series
all uses Genesys Logic chips and/or Philips CP2155BE front-end. But
some of the CanonScan series are still apparently unknown, and it
would be fantastci if one or more of those used an existing protocol.

Is there anyone who would be able to sniff a Windows USB log of the
following scanners:

* CanoScan 4200F
* CanoScan 5200F
* CanoScan 9900F
* CanoScan 9950F

Alternatively, opening up the scanner and listing all the chip
information :-) But a sniff will be enough to get quite a bit of

I see there appears to be a driver on Sourceforge, but I have no
knowledge of what it can do:

Many thanks,
Gernot Hassenpflug
