I have build the powerswitch with an ATmega8, changed the config file for the firmware. The Pins are the same as the original ucomputer.
After flashing the firmware the hardware is not shown in my usb device list.
I am working with MacOS X 10.6.8 AVR GCC from Objective Developement.
I flashed the hardware for a test with the USBasp firmware and that works.
Have anyone a idea?
