RX/TX led not blinking in USB-CDC

[cmaglie]

Update bootloader and USB-CDC driver in order to turn on RX/TX leds when there is serial activity.

here's some CDC USB LED implement code you can use to try this out:

tested on a zero (but of course, plz also test :)

@ladyada thanks for the link :)

I've opened PR #121 with something similar, it will make the LED's blink for all native USB traffic (including CDC), just like the Leonardo.

#121 works. It blinks the USB TX and RX LEDs during serial communication. I tested the directions above. However, this doesn't address the issue where the LEDs don't blink when uploading a new sketch. I imagine this will need to be added to the Arduino Zero bootloader.

@rory-littleBits great thanks for trying it out!

I imagine this will need to be added to the Arduino Zero boot loader.

Yes, #121 only handles the non-bootloader side, #1 is open to track this feature in the boot loader.
