do you have an USB adapter in your computer? If so, could you try

is very unlikely because others have reported success with this 

What kind of error message do you see on the console? Is the SCSI
bus terminated correctly? Which Adaptec card are you using? Are there
other devices on the SCSI bus besides the scanner?
