well i can necessarily say after jtag. i'm not sur they were working before. but here is what happen. i didn't have a powerbrick for xenon, so i broke out the center piece in the power port and used a falcon powerbrick instead. every thing works except the usb ports. could i have triggered the failsafe for too much voltage which kills power to the usb ports to avoid damaging external components? could the jtag be drawing too much power away from the ports? any ideas?
