driver to interface AVR chip with USB port, compile with WinAVR, very cool

Atmel CPUs come at internal 1Mhz clock. To use USBasp you need to use a SPI clock under 1/4 of the clock, menas under 250Khz. By default the USBasp uses 375Khz and is unuseable for new AVR CPUs. This file (must rename to usbdrv.c before compile) is f
