[sdiy] PIC / Atmel Programmers (usb)

[Bert Schiettecatte]

I came across that one too. Unfortunately USB requires strict timing. If you
run something else on the AVR that messes up the USB timing signals, you're
in for a lot of trouble at the OS side I think...

For those who want to go the really hard way, check out this one:

No need for "true" USB controllers as you can do it with a standard AVR
(depending on your application); the described circuitry offers

- LowSpeed USB port (1.5MBit/s)
- standard serial port with changeable baud rate
- infrared (IrDA) port
- programmable 8-bit I/O
- 128 byte EEPROM

Windows users will especially like it since there's already a driver w/
documented API for it.
