I believe these (and the A3Us) use a slightly updated JTAG ICE protocol, which avrdude does not currently support. I had promised Joerg Wunsch to send him some traces from Atmel Studio programming these new chips, but haven't gotten around to it. If you have the capability to program these with Atmel Studio and get USB traces, these may be useful to Jeorg to add support for these.
There is also another way, using DFU functionality. There is an experimental patch to do this: https://savannah.nongnu.org/patch/?7896 But this also needs testing.
