The scanner is plugged in at the back and is not recognized anymore. It 
definitely worked early january (FC3 on actual patchlevel), and then I 
used the scanner for the last time mid january. Now it is difficult to 
go back to that patchlevel.

I'll go back to that at last resort. My Olympus digital fotocamera e.g. 
works perfectly, it might be connected through USB 1.1.
