I do not understand the reason for adding another LED device, nor why
you think it helps. When I added the LED code, I wanted to get the LED
to indicate that there was I/O activity, which is why I chose the TX
and RX LEDs. Choosing "on" as the default state when there was no
activity and blinking it "off" with I/O seems to give exactly the
right behavior. Unfortunately, the asynchronous behavior of the USB
operations makes it very tricky to get the shutdown right.
