  • No USB after engine start

    I've discovered lately that sometimes if I turn off my engine, keeping the car and PC on, and then turn the engine back on results in loss of USB (I've observed loss of touch on my screen and no GPS signal -- they're on different usb ports). This hasn't always been this way, but I have no idea what I changed that might've caused it. Restarting the computer fixes the problem. Any ideas?

    Perhaps a faulty power supply? Maybe your 5volt rail is unstable.
