--- Comment #5 from Stefan Reichardt <fbi.sr at gmx dot de> 2012-02-22 01:38:52 UTC --- Its no problem to compile and link it that way but i dont have that device so cant test it. I would make a patch myself and post it here and on binutils, if i knew that this would only involve copying some lines from the devices without USB support. Some devices like xmega128A1U are already there so i suppose all functionality for the new USB devices is already in the code. Maybe you or Eric could give a short statement about this? Stefan
