Thanks for the reply. I removed the battery holder from the board and did a detail cleaning and inspection and couldn't find anything obvious. This time I did notice a message pop up in the lower right corner on my Windows XP monitor (by the task bar) that leads me to think you might be on to something. It probably appeared before but I didn't catch it. The message reads:
Power Surge On Hub Port: A USB device has exceeded the power limits of its hub port. For assistance in solving this problem, click this message.
The message goes away too quickly to click on it but then I couldn't click anyway since my mouse gets disabled while the Coobro is plugged in.
While plugged in, the FTDI chip does not get warm. It stays cool.
I attached a set of images for more information:
Corner view of board by FTDI connector.
Underside of Coobro board. I can't find any soldering problems.
I'm not sure what to do next since I can't find any shorts.
