Hello everybody,

first, excuse me for my bad English ...

Three month ago, I bought a AGFA scanner (SnapScan e20).
Looking in Sane-backend, I saw that it was supported.

I installed the last version of Sane (1.0.6) and the last backend for 
the snapscan model.

*)When I do: #sane-find-scanner -v
the response is

/*...
sane-find-scanner: searching for USB scanners:
sane-find-scanner: checking /dev/usb/scanner... failed to open (status 4)
sane-find-scanner: checking /dev/usb/scanner0... open ok, vendor and 
product ids were identified
sane-find-scanner: found USB scanner (vendor = 0x06bd, product = 0x2091) 
at device /dev/usb/scanner0
...
*/
Ok, the vendor and the product id are correctly found.

*)When I do: scanimage -d snapscan:/dev/usb/scanner0
the response is
*
/[sanei_debug] Setting debug level of snapscan to 255.
[snapscan] sane_snapscan_init
[snapscan] sane_snapscan_init: Snapscan backend version 1.4.7
[snapscan] sane_snapscan_init: configuration file not found, defaulting 
to /dev/scanner.
[snapscan] add_device(/dev/scanner)
[snapscan] add_device: Detected (kind of) a SCSI device
[snapscan] add_device: error opening device /dev/scanner: Invalid argument
[snapscan] sane_snapscan_init: failed to add device 
"/usr/local/lib/sane/libsane-snapscan.so.1"
[snapscan] sane_snapscan_open (/dev/usb/scanner0, 0xbffff2e4)
[snapscan] find_device
[snapscan] sane_snapscan_open: device "/dev/usb/scanner0" not in current 
device
list.
scanimage: open of device snapscan:/dev/usb/scanner0 failed: Invalid 
argument
[snapscan] sane_snapscan_exit/
*
It say that the device "/dev/usb/scanner0" is not in current device list 
??????

*)My snapscan.conf file looks like:
/*
# If not automatically found from above, then you may manually specify
# a device name.

# For USB devices, make sure that the name contains 'usb' somewhere, as in
# '/dev/usbscanner' or '/dev/usb/scanner0'. Do not use a link
# from /dev/scanner to your USB device.
# For SCSI, use the generic device (e.g. /dev/sg0 in Linux).

#/dev/sg0
#/dev/usbscanner
#/proc/bus/usb/devices
/dev/usb/scanner0

# Change to the fully qualified filename of your firmware file, if
# firmware upload is needed by the scanner
firmware /home/philippe/Snape20.bin
#agfafirm -v /dev/ubs/scanner0 /home/philippe/Snape20.bin

*/*)Is it mandatory to upload the firmware with /*agfafirm*/ if I use 
the last SANE version ???,

*)Once, when I done: scanimage /*/dev/usb/scanner0*/ , the scanner has 
moved and a lot of strange characteres appered on the screen. It was not 
impossible to read the prompt after. I had to close the console !!!

*)If /dev/usb/scanner0 is my device, what have to be the permission of 
scanimage, /dev/usb/scanner0, ...

*)With usbview, I saw the scanner.

My distrib is Mandrake 8.0
Kernel 2.4.16

If someone can show me the good way, it would be very nice.

Thanks

Philippe Reis
