Hi Andras,

Ok, I tried following today:

1. I disabled all backends but coolscan2 from the dll.conf file. 
Unfortunately no sucess here.

2. I used VueScan 7.5.29 and was able to get 2 previews out of it, but 
as soon I tried to get a regular scan I run into the same problems like 
before:

May 29 00:45:52 euler kernel: usb.c: registered new driver usbscanner
May 29 00:45:52 euler kernel: scanner.c: probe_scanner: User specified

3. Then I changed the USB cable between the scanner and my PC. But also 
no success.


I noticed another strange thing. As soon as I invoke a
modprobe scanner
I never be able to remove the module again.

Any help is appreciated. I can't believe that I have to install Windows 
on one of my PCs to make the scanner work.

Thanks in advance,

Erik
