As a matter of course, I've changed my USB stuff, including my hub, 
since the problem appeared.

It happens only occasionally. If it worked properly 100 times in Safe 
mode or another account, that wouldn't prove anything.

I have 10 extensions, all for my Samsung USB drive. I had the problem 
before I got the drive.

I sleep my computer dozens of times each day. It hasn't malfunctioned 
since right after I restarted June 15. It probably wouldn't happen at a 
Genius Bar.

When it malfunctions, I've noted the time and tried to find something in 
the system log. I haven't found it.
