Sorry not sure where your getting at90usb82 or ATmega8?
You do have the Qidi 1?
The avrdude command line should look something like this just with a different path that matches your computer.
To add the bootloader it should look like this. Path in Red
avrdude -p m1280 -F -P usb -c usbasp -U flash:w:bootloader/atmega1280.hex \ -U lfuse:w:0xFF:m -U hfuse:w:0xDA:m -U efuse:w:0xF4:m -U lock:w:0x0F:m
