But at tis point Linux found the scanner and created the device node and an 
entry in /proc/scsi/scsi and the scanner is turned on and connected. With 
previous kernels this was sufficient to actually use the scanner.

I don't think it is stale, looks more like it is not fully initialized. But 
maybe the SCSI implementation of the scanner is buggy and recent kernels 
trigger a bug. The scanner is a Mustek ScanExpress 120000SP and I don't think 
it is 100% SCSI compatible...

Hope, this bug will be fixed soon... I usually turn my scanner on when I need 
it and not during system boot. 

Thank you for your help!
