LinuxQuestions.org - Epson Perfection 1250/Photo USB flatbed scanner

Hi there,
I can't resolve a usb-scanner problem. I have checked all the sane, xsane sane-backend man pages but still I get an error message when I start xsane or xscanimage or scanimage like: device busy.
I run a debian like system KNOPPIX 3.
Linux pam 2.6.11 #2 SMP Thu May 26 20:53:11 CEST 2005 i686 GNU/Linux

There is an interesting thread but they came to no result.

Here you mey find some output they show that the scanner is recognized by the OS.

geo@pam:/home/geo$ sane-find-scanner

# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04b8 [EPSON], product=0x010f [EPSON Scanner 010F], chip=LM9832/3) at libusb:002:004
# Your USB scanner was (probably) detected. It may or may not be supported by

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports

geo@pam:/home/geo$ scanimage -L
device `plustek:libusb:002:004' is a Epson Perfection 1250/Photo USB flatbed scanner

The device files are like:
crw-rw-rw- 1 root scanner 180, 48 2002-07-14 07:55 /dev/usb/scanner0
crw-rw-rw- 1 root scanner 180, 49 2002-07-14 07:55 /dev/usb/scanner1

while user geo is a member of group scanner!
There is no link from /dev/usbscanner to /dev/usb/scanner0, because that can create trouble.

/etc/sane.d/#Epson 1250 plustek.conf has been updated in regard to the vendor and device id:
device /dev/usb/scanner0
[usb] 0x4b8 0x110

In /etc/fstab one can find:
usbfs /proc/bus/usb usbfs devmode=0666 0 0
none /proc/bus/usb usbfs defaults 0 0
There is no kernel module "scanner" on the system.
I hope I gathered all neccessary information in order to aks for help.

Thanks in advance
