Most laptop and desktop computers have limits on the current you can draw from the USB port.

Some new devices might want more current than that limit. For charging purposes. This might have damaged some usb or power circuitry.

I have not looked in a while....but they use to have cheap usb monitors.....that would display voltage and current of usb port, while in use.
