Interesting idea.  I'll check that next time I power down.

Physical.

Seriously?  I mean, I certainly don't mind trying it and it wouldn't be any 
harder than pulling the cable to check the pins, but what's your line of 
thinking here?

Last night I bumped it down from 40MB/s to 20MB/s, disabled tagged queueing 
(which the adapter had enabled by default), and moved it to a different power 
lead.  So far so good, but 24 hours does not my confidence earn.  Thanks for 
the tips!  If it's still acting wonky, I'll work through them.
