[sane-devel] Sanning from command line - need find out correct device name

[rog70]

PC: Debian Etch, samba + CUPS server (no GUI), sane-utils installed
3 printer on CUPS:
1. Samsung CPL-500 color laser
2. HP DeskJet 5150
3. Samsung SCX-4200 (all-in-one)
CUPS is handling the 3 printers without fuss -> raw queue, windows drivers
on the clients

scanner: Samsung SCX-4200 multifunctional device, (laser printer + scanner). 
Id like to share the scanner with saned for the WinXP clients. I DO NOT want
scan from the linux box directly.

installed the latest Samsung unified Linux driver. It complained a little
about the lack of X, but finished without problem. installed sane-utils.
Problems:

-sane-find-scanner find the scanner
-scanimage -L output:
device `smfp:SAMSUNG SCX-4200 Series on USB:1' is a SAMSUNG SCX-4200 Series
on USB:1 Flatbed Scanner
-lsusb output:
Bus 004 Device 040: ID 04e8:341b Samsung Electronics Co., Ltd 
Bus 004 Device 037: ID 04e8:3248 Samsung Electronics Co., Ltd 
Bus 004 Device 001: ID 0000:0000 
Bus 003 Device 017: ID 03f0:6204 Hewlett-Packard DeskJet 5150c
Bus 003 Device 001: ID 0000:0000 
Bus 002 Device 001: ID 0000:0000 
Bus 001 Device 001: ID 0000:0000
first: SCX-4200, second:CPL-500

-BUT when i try scan from comand line (for testing purpose only):
scanimage > /tmp/image output
parport 0x378 (WARNING): CTR: wrote 0x0c, read 0xff
parport 0x378 (WARNING): DATA: wrote 0xaa, read 0xff
parport 0x378: You gave this address, but there is probably no parallel port
there!
parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE]
lp0: using parport0 (interrupt-driven)

and the color laser wakes up from sleeping. I seems to me, that the pc
probes the wrong port for the scanner. I tried "scanimage -d smfp" without
any success. I cannot find out the corrent device name for the SCX scanner.

Im a newbie in sane (and USB devices), so any help will be greetly
appreciated. 

Thanks
Roger

PS: sorry for my poor english.
