Jerry Roletter / USBDevice

Modified USBDevice mainly for debug of serial port communications. It is unfinished and should not be used - use the main branch.

I'm trying to commit this project for school.  I made minor mods to USBDevice for debugging mostly.  I hope it doesn't get mixed with the "real" USBDevice code.  If so I'll figure out how to un-do (this is my first time with mbed revsion control).
