• ATmega32U4 (PJRC Teensy 2.0)
• AT90USB1286 (PJRC Teensy++ 2.0)
• AT90USB1287 (Atmel USBKEY)
• ATmega168P with using V-USB
• ATmega328P with using V-USB
• ATmega32U2
• AT90USB1286, 646, 647 should work
• AT90USB162 testing...

NOTE: To enable full features of firmware you'll need 32KB flash size.

Please add any tested microcontrollers to this list.
