[bilal shareef]

Hey,
I am trying to make USB ASP burner for AVR controller. The problem that I am facing is that after dumping the firmware in atmega8 when I connect it to my PC's USB port the PC doesn't recognize the device.. It says that its an unknown device. Please help me what should i do to fix this problem. Bellow it the link which contains the firmware and schematic of the burner..

1) Check the connections once again

2) Did you tried proper fuse settings?

3) What is the OS did you tried(e.g. win xp, win 7)?

Check the above and come up with results
