I have an Iomega Buz, which has a built in Advantec UltraSCSI adapter. Now my scanner is my only SCSI device and it used to work fine. The card reports back fine on boot, but if I have the scanner plugged in I get "Error 0x15". Windows device manager reports the card having trouble even with a driver reinstallation(whether something is plugged in or not). Is the card hosed? Yes, I tried another slot, it worked fine the last time I hauled out the scanner 2 years ago.
