Microtek ScanMaker V310

[John Dalbec <jdalbec@cboss.com>]

I have potato, kernel 2.2.13, ppSCSI driver patch.
I typed 'xscanimage' and tried to do a preview scan.
What a noise!  I opened the scanner and the light bar
was shaking back and forth like it had Parkinson's.
I'm concerned this could damage my scanner.
Yes, I have done preview scans under another OS
and they were not so noisy; also faster, I think.
Here is the text output from xscanimage:
