Hi everybody,

I like to announce the release of a backend for the HP2200C scanjet. 
This scanner is equiped with a LM9832-scanner-on-a-chip. This chip is 
also part of the Epson 1250 and verious canon scanners. The backend is 
developed for the HP, but at this moment work is being done at porting 
it to the Epson too. 

The driver is available on: 
www.xs4all.nl/~stwerff (sorry for the empty site, just opened it 
today;)

Please look at the source and (if possible) test it.
It features: 
-SANE compatible (installation-instructions in tarball)
-scanning at 600/400/300/200/100/75/50 dpi
-scanning at 3x8 bpp color and 8 bpp grayscale
-A separate config file for online tuning of timing and gain.
-Use of the sanei-usb functions for detecting the scanner
-Similar SANE interface as the sm3600 scanner.

Known bugs:
-minimum maxlen of saneread() related to amount of byte per line.
-slightly off-tuned 600 dpi.
-black and white support still broken
-cancel behaviour not yet docile:)
-too little documentation

Greetings,

Ludo Stellingwerff
