I have a MIcrotek ScannerIIsp installed on a windows 7 home premium system (32bit). Using an Adaptec 2920c SCSI card. All drivers for the SCSI are installed and also for the scanner (surprised they still had them). Unfortunately the scanner program(s) don't recognize that the scanner is there. Under Device manager everything shows ok. I'm thinking that I'm missing a twain compliant driver somewhere. Any ideas?
