/diy/ - Do It Yourself

>>1379565
Ok guys, more troubleshooting to come.
Apperently the microcontroller is working alright.

Yesterday I wanted to try out this module we made in uni in first semester and do something with it. As retarded as i am i didnt notice that it was laying like pic related on a metal plate and connected it to USB.
To that point it was still working and afterwards the function was okay. EXCEPT that the usb wasnt working anymore.
Thats when I tried reflashing the firmware and fucked up the fuses. Fuses should be alright now. Still the USB does not work. Are the zener diodes likely do go ded when shorted?
If that's not the case then i still might have some firmware problems.

Though, when I flash the atmega with a programmer everything else seems to work perfectly fine
