Hi,

I had to reformat your message because it's HTML again. That's the
last time I respond to a HTML-only email.

Maybe I got the ids mixed when adding them to the kernel scanner
driver. What I have is:

| /* Fujitsu */
|   { USB_DEVICE(0x04c5, 0x1041) }, /* fi-4220c USB/SCSI info:mza@mu-tec.de  
|   { USB_DEVICE(0x04c5,0x1042) }, /* fi-4120c USB/SCSI info:mza@mu-tec.de
|   { USB_DEVICE(0x04c5, 0x1029) }, /* fi-4010c USB AVision info:mza@mu-tec.

The "41" and "42" may be a coincidence but it may also be an
indication for a mixup.

All the following is just guessed, I'm not the fujitsu maintainer:

fujitu.conf is set up correctly? I guess you need to add something like
"usb /dev/usb/scanner0".

I don't think so in this case. You need the newer versions if you want
to do autodetection using the vendor and product ids. For manually
setting the device file name it should work.

I don't think so, either. Looks like the backend soen't check the ids
at all.

Ususally it doesn't help to reinstall anything. Setting up software
may help :-)

If setting up fujitsu.conf doesn't help, show us the output of
SANE_DEBUG_FUJITSU=255 scanimage -L
