#46 snapscan e20 don't work

spanish and my english is little)

I have a Debian SID system.

I did every steps.

I did installed sane 1.0.5-3 from SID distribution of
Debian.

I downloaded firmware from agfa.com and copy this in
/etc/scanner/Snape20.bin

In /etc/sane.d/snapscan.conf i put:

/dev/usbscanner
firmware /etc/scanner/Snape20.bin

I recompile kernel with option "m" in CONFIG_USB_SCANNER.
kernel version: 2.4.17

then

scanimage
[sanei_debug] Setting debug level of snapscan to 2.
[snapscan] add_device: error opening device
/dev/usbscanner: Invalid argument
scanimage: no SANE devices found

Hi,

sane-1.0.5 does not support the automatic downloading of
the firmware. You'll need to run "agfafirm" manually.
However, since sane-1.0.5 contains a number of other bugs
in the snapscan backend I recomend to upgrade to sane-1.0.7.

Concerning the "invalid argument" error: Did you specify
the vendor and product id while loading the scanner module?
Also check the permissions on /dev/usbscanner. If none of
this helps, increase the debug level to 255 and send me
(oliverschwartz@users.sourceforge.net) the output.

Regards,

Oliver

Hi,

this is a different problem. The scanner reports a hardware problem. From
my docs the error code means "Line motor error" and "Lamp or CCD
error". Are you sure your scanner is o.k.? Maybe you have to remove the
transportation lock?

The permissions on /dev/usb/scanner0 are o.k if user baggypants is the only
user that may access the scanner. Otherwise you can allow global read /
write access to the device. You can also create a new group, add group
read / write access to the device and add all scanner users to the group.

Regards,

Oliver
