Looking for a freelancer to build a driver for the Corex Cardscan 60 which uses
the lm9832/3 chipset.

Hello,
I'm back from a 2 weeks holidays. The support for HP2400 isn't
progressing
fast since I don't have access to such model. However, I'm in the process to
document how to add support for it, and doing some modifications to the
genesys backend. Current CVS version has support for the 2400C in warm up.
Tests and code finalization is left to people having a device to work on, and
willing to do it.
With the latest version of the documentation and code (at
http://perso.modulonet.fr/~stefdev/sane/gl646-wip03.odt), there should be
enough information to get warming up working. The 2 functions to test and fix
are:
- gl646_init_regs_for_warmup
- genesys_warmup_lamp
The set up of the scanner in the backend log will have to match this
(extracted from usb logs):

a few differences are OK, for instance the code in CVS will use 2668
pixels
instead of 2770.
