So I have an at90usb1287, the first time I plugged it into the pc, the pc said unrecognized device but did not prompt me to install drivers. I thought whatever; I'll use my ISP header. Connecting an AVRISP MkII results in a green light on the AVRISP but AVRstudio gives an error that it can't enter programming mode! I've tried different cables and that doesn't work. Did I somehow fry the chip the first time I plugged it into the pc? That was the only time the pc ever gave a response to the board being plugged in.
