Hi,
I'm using cvs as of a few minutes ago. But nothing. :(
This is on debian unstable. With 2.4.17 with the low latency patch. The
firewire card is OHCI compatible with via chipset. 

The scanner turns up fine in /proc/scsi/scsi and is found by
sane-find-scanner

The only other scsi device I have isn't really scsi it's a ide cdwriter
which uses id-scsi so it's possible something isn't right in the kernel
but sg is complied and loaded.

The permisions are fine. Running scanimage as root makes no difference.

Running scanimage -L only list my video capture card (the out put of
sane-find-scanner can be found in a previous mail)

scanimage -L
device `v4l:/dev/video0' is a Noname mgacap-0 virtual device

which I can scan from fine

trying to specify the deivce gives the following error:

scanimage -d epson:/dev/sg0 --preview yes
scanimage: open of device epson:/dev/sg0 failed: Invalid argument

The only line in my epson.conf is 

scsi EPSON

I have no idea what to try
The logs all look fine to my inexpert eye.(I even tried rebooting :( )

Any help is greatly appreciated.

thanks
