Poor or missing parts. Cheap components. Defective design. Damn, I want 
a whole new monkey. :D

Huh. Tho this still sounds like a hardware problem.

I have one of those Renasas add-on ports with front and back access. 
I've discovered that for the front ports, only one of the two will work 
at a time, at least on this box. Might be affected by some issue in the 
mainboard's own USB, which only about half works. Southbridge bug, 
maybe. (Was gifted two of the same board, and one was marked "bad 
southbridge" tho now that one seems to work. Maybe both of 'em...)

USB self-grounds before the powered part makes contact, so shouldn't be 
an issue. Tho note that headphones would have been a sudden power draw.

You might want to get one of those little blue pass-through USB testers 
that show voltage and draw, and check if there's a sudden power drop, or 
worse, a spike. Also I would look at voltage on the system power supply 
-- I have a tester that displays it for each rail, but voltage reads 
might be in your BIOS under "PC Health" or something like; maybe try 
hotplugging the offending USB device and see if voltage jumps. If the 5v 
is out of whack, that would affect some USB devices.

Only at Ky's House: only reason I've had the linux box up in the last 
month was to run updates. And then run updates on its baby brother in 
the VM. This is silly. :P
