Aha! This would appear to pose a problem! So on to my next question:
what does a scanner driver look like and how do I go about getting it to
recognize my scanner?

Is there just one driver for all the USB scanners?

Right, I did that, but see above concering my missing driver!
Thanks for the pointers, I appreciate the help!
