Are you pressing the reset button to start the bootloader?

Yes, when I press the reset button a /dev/ttyACM0 appears in my computer, I do:
- Press and hold the reset button
- Click in Upload IDE button
- Release the reset button when "Uploading..." appears in the Arduino IDE

hmm we don't use the leonardo bootloader on the atmega32u4 - we use the avr910 bootloader that came with it. does it enumerate at all on USB?
