The header files for the ATXmega64a1U and ATXmega128a1U incorrectly specify the vector for USB_TRNCOMPL_vect as '127' when it should be '126'. Other headers for similar CPUs have it correctly assigned as 126. This was seen in both versions 1.8.0 and 1.8.1, and is probably the case in earlier releases. The ATMel Studio files also have the vector assigned as 126, as it is with other USB-capable xmega processors (such as in iox128a4u.h, etc.). Only the 64a1u and 128a1u headers seem to have this problem.
