[Elecraft] P3 "USB DEVICE REMOVED"

[Brendon Whateley]

I'd try a different USB keyboard. It may be that your keyboard doesn't boot
up fast enough or has some other timing issue with the P3 USB device
enumeration procedure.

USB isn't a simple serial connection. And a Keyboard is a computer. Welcome
to the modern world.
