Can't compile for Teensylu

[lincomatic]

I set MOTHERBOARD = 8 in Configuration.h.
In Arduino, I compile for Teensy++ 2.0.

I get errors:

Teensy's HardwareSerial.h doesn't define rx_buffer, so that causes the first error.
the compiler's iousbxxx6_7.h which contains register defs for the AT90USB1286 doesn't contain UCSR0A, etc. which causes the other errors

I will try to implement the USB part. It was lost when we changed some part in the serial communication.

[ErikZalm]

I added the teensylu functions. It now compiles.
I can not test it because I have no teensylu, but in theory it should work.

Thanks. I'm waiting for mine to arrive, and will let you know if it works once I've tested, unless someone else jumps out first
