This project is an AVR programmer using ISP protocol.
The differences is this programmer use HID, so no Windows driver needed.
The schematic uses common USBASP schematic.
The MCU HID driver using VUSB library from obdev.
The devices list in this sofware is limited to most used MCU and all of those devices was bench tested.
No problem found on the test.
This version is Beta so maybe a or some bugs in the software.
So please let me know if bugs found for improvement.
