I finally had some time again to use my Heidelberg. I got an Adaptec 2930LP-SCSI-card which can be used under Win7 64Bit (and works according to Silverfast).

But when I try to run the Silverfast Demo (which worked fine on my previous PC with Win XP and Adaptec 2940), it is unable to detect the scanner!?

Device-Manager and logfile confirm that the SCSI-card recognizes the Scanner:

SCSI devices
Description: LinoHell TANGO Scanner SCSI Processor Device
Path: \Device\Scsi\adpu160m1Port1Path0Target5Lun0
Low-level name: SCSI\ProcessorLinoHellTANGO_Scanner___1.0_


Help! What else can I try? Thank you!
