Ignoring those as they appear to be from when the scanner was detached.

Okay.

That's from uscanner_attach in uscanner.c, and it quits there.  But is 
it due to a firmware-less scanner or FreeBSD USB code?

You should probably say exactly what brand and model of scanner you're 
using.

For that vendor and product, I only see the one entry.  But it's one of 
those scanners that needs a firmware download, gt68xx.  Maybe on those 
you have to use ugen to load the firmware, then load uscanner?  I plead 
ignorance due to lack of hardware to try.

Use of scanners that need firmware uploads is probably an area that 
should be expanded in the Handbook.  At present, it's mentioned but just 
refers to the sane driver man page, which in this case is 
libusb-specific.
