That's how you kill a USB port 101
Why would it kill the port? I think the power lines would be at equal voltages on both ends and the data lines just wouldn't do anything.
Not exactly equal. One will try to feed to another which can kill it. It's not made to be connected like this. Maybe they could even fight if it tries to compensate by increasing voltage.
But hopefully there's some protection that disables the USB port before something ugly happens.
This is entirely dependent on how the circuitry is set up. However USB voltage is always 5 volts and the controller doesn‘t go over that.
Do you mean that it was risky connecting one pc to another with this usb to usb cable ???
