Sorry if this is the wrong place...  Anyways, I have a development board with an AT90USB82 chip.  IS there any way to flash the Arduino bootloader and firmware onto it?

Maybe.

Does the development board bring out the USART pins?

Does the development board bring the the serial programming pins (RESET, PDI, PDO, SCK)?

The AT90USB82 is functionally equivalent to the ATmega8U2 which is used on some older Uno and Mega boards for USB to serial conversions.  It should have the DFU bootloader on it.  So you could use FLIP to upload code to it.  It should also have the ISP pins available for programming via ICSP.  Don't know if anyone has done an Arduino bootloader for it.

Coding Badly:  The dev board actually has all of the pins in use, I would have to modify it a bit -- It should have all of the pins broken out.

Hiduino:  That would be assembly code, correct?  I could do that, but writing the code I have in mind in assembler would proabaly be harder than just building a Leonardo-compatible.
