I posted on the input club forum already, figured I'd try here.
"Just today, my left hand keyboard started going into a reset loop. I quickly discovered that the case was hot to the touch. After some testing, I have determined that the chip marked ‘U1’ on the pcb board becomes hot to the touch within 10 seconds of plugging it in. This is on the Rev 1.1d board."
I actually found a post from about 15 days ago on the forum reporting the exact same problem, with no responses, so at least I know it's not just me. I tried re-flashing with the latest drivers, no go, although the keyboard works just fine as far as sending inputs, at least until it gets so hot the heat cut off shuts it down and it goes into a restart loop.

Sounds like something is either causing a short or an excessive amount of voltage is going to U1. A part or parts (i.e. resistors, capacitors, and/or transistors) along a circuit could have failed which would cause the excessive heat. If U1 is some kind of microcontroller, it's rated to handle X amount of heat before shutting off to prevent damage.
If you can get a hold of the schematic and use a voltage meter to check what the readings are going to each pin of U1, you might be able to find the problem. Find it is most of the battle, actually fixing is easy.
