I can run my LiDE 80 from Canon's "Toolbox" application but Image Capture doesn't see the device. I asked Canon support about it. Alas, no help...

That is very strange that the CanoScan LiDE 80 would scan using the
Toolbox but not from Image Capture. The CanoScan LiDE 80 is not
supported on the Mac OS X 10.5 Leopard OS. We are sorry for any
inconvenience this may cause.
The following models are compatible with Macintosh OS X 10.5: 4400F,
8400F, 8600F, 8800F, 9950F, LiDE 25, LiDE 35, LiDE 60, LiDE 70, LiDE 90,
LiDE 500F, LiDE 600F.
