Ok, I did it, but this gives no other results (it
still only prints the error message). I tried
SANE_DEBUG_DLL and I've got something there. But IMHO
nothing seemed strange. I can send the results if
someone wants me to do so.

Maybe the kernel, but I'm not sure. If there was a
change it was a minor one. The backend did certainly
not change.

scanimage -L shows me this, so I assume it's right
what I'm doing. Anyway it worked before like this.

Sorry, I'm not an expert. Could you explain this to
me?

Thanks for your help
