Hey there, I hope you won't get the message twice .. I used the wrong
outgoing SMTP server on my machine so the mailing daemon did not
recongize my account ... here we go a second time


I got the following problem:

I have a SnapScan e20 USB Scanner at home and tried to get it running
but failed:

- I run SuSE 7.2 Professional
- I followed the instructions @ http://snapscan.sourceforge.net/
- I recompiled SANE with the patched snapscan backend files and
installed it

# sane-config --version
1.0.5

- I changed the header Files as described in <kernel>/drivers/usb/scanner.h

struct usb_device_id scanner_device_ids [] = {
...
/* Agfa */
{ USB_DEVICE(0x06bd, 0x2091) }, /* SnapScan e20 */
{ USB_DEVICE(0x06bd, 0x0001) }, /* SnapScan 1212U */
{ USB_DEVICE(0x06bd, 0x0002) }, /* SnapScan 1236U */
{ USB_DEVICE(0x06bd, 0x2061) }, /* Another SnapScan 1212U (?)*/
{ USB_DEVICE(0x06bd, 0x0100) }, /* SnapScan Touch */

- I recompiled my kernel: version 2..4.10 --> USB drivers as modules
- Inserting the scanner module succeds

bash-2.05# lsmod
Module Size Used by
scanner 7264 0 (unused)
...
usb-uhci 21216 0 (unused)
usbcore 47040 1 [scanner hid usb-uhci]
...


- Uploading the firmware seems to work:
BUT: the scanner flasshes the lights, moves something internaly, then
the lights are OUT, after some tme it turns on again ? Is that normal?
bash-2.05# modprobe scanner
bash-2.05# agfafirm -v /dev/usbscanner /opt/snapscan/snape20.bin

- I changed the /etc/sane.d/snapscan.conf File:

bash-2.05# more /etc/sane.d/snapscan.conf
scsi AGFA
scsi COLOR
scsi ACERPERI

/usr/bin/agfafirm -v /dev/usbscanner /opt/snapscan/snape20.bin

# If not automatically found from above, then you may manually specify
# a device name.
#/dev/scanner
/dev/usbscanner
#/dev/sga

- now when I run xsane it starts up and finds the scanner (seems to ...)

hermaf at hermaf:~ > scanimage /dev/usbscanner
scanimage: sane_start: Device busy

hermaf at hermaf:~ > xscanimage /dev/usbscanner
--> Failed to open device '/dev/usbscanner': invalid Argument
hermaf at hermaf:~ > xscanimage snapscan:/dev/usbscanner
--> Failed to open device 'snapscan:/dev/usbscanner': invalid Argument
hermaf at hermaf:~ >xsane
--> Scanning for device
--> xsan: No devixe available

Someone knows what to do or what is wrong ?

Thx Felix
