So I had a couple of ATMEGA32U4s lying around the house and I thought why now make a Leonardo for the odd prototyping purposes. The schematic is attached here (its not really a Micro, just the named is erroneously and never bothered to correct it). Now after building the board, first I used the Pocket AVR Programmer to flash the 32U4 with the Arduino bootloader (using Sparkfun's excellent hookup guide). This went without a glitch and I did not get any errors. However, after this when I connect the standalone board, The TX and RX pins are on all the time and I don't think new HID+COM ports are being created for the device since the Tools > Ports is greyed out. What am I missing here?
