Due to the recent contact AVR32uc3b0256

Contact engineering program is based on ASF1.4 (2010) the library USB CDC change, then the corresponding is the IAR FOR AVR32 1.31 (2010)
Now I use the IAR FOR AVR32 4.30

Redefining a E27 program mistakes due to the old, so I began to think IAR setting where was wrong, really change not to come out to have a try after official CDCexample procedure, or in the wrong, so it should be high to low versions where there are changes don't know the compilation,

Want to help there you didn't meet this kind of situation,
