Ahh, great.

IC. I chose Atmels because they were well supported by Linux: Compiler,
programmer software, connection via parallel port. What USB
microcontrollers are good for Linux? Full or high speed. I'd like to
sample random bits from avalanche diode noise and get it into a PC (via
USB). And maybe make a BIOS chip programmer (LPC PLCC32), as I can't
find a compatible main board to hot flash my chip and I don't like to
pay for having it done (only 10e, but still). Maybe I'll use the serial
port for this.

Yes, only dual inline for the bread board.
