Hi everyone,


I'm posting here for the first time. So, please be gentle with me (and
for my poor english, please :-)

The first reason why I'm here is because I've got a CanonScan FS4000US
(think USB and SCSI), and this hardware doesn't work yet on Linux.

Thank you Canon :-(

Of course, I *really* want to do something...

For this, I'm using both Linux, Mac OS X and Windows. The two last come
with native provided drivers for their respective OS :-/ , so I can
install this scanner on this one and obtain a lot of informations about
drivers that are used, and so on.


My purpose is to find someone who can help me to write/complete a driver
for this hardware and perhaps include it in Sane (what a good project ,
no ?).


Be careful, I'm not a programmer, but I think know enough Linux to do
this without lose to much time. I often compile/modify kernel sources to
make my hardware working since 6 years for now.


State of art about this hardware :

1) This hardware seems to be known in the kernel sources, because I
found it in /usr/src/linux/drivers/usb/scanner.h

eric at popom:/usr/src/linux/drivers/usb$ cat scanner.h | grep FS4000
	{ USB_DEVICE(0x04a9, 0x3042) }, /* FS4000US */

2) It's not known in sane-backend


3) modprobe scanner on my ibook (Debian sid, kernel 2.4.22pre4-ben0), I
can read, with  :
