What are the voltages for each USB 3.0 header pin of Aspire ATC-710-EB51

The two USB ports at the front panel of my Acer Aspire ATC-710-EB51 stopped working, so I decided to unplug the USB to motherboard cable and test the USB 3.0 header pins with a multimeter to determine if the cable is the problem or the header. When I checked the voltages of each pin, I got almost 5 volts for pins 1 and 19, and I didn’t touch pins 4, 7, 13, and 16 since they’re ground. Pin 11 had a little over 1 volt, pins 2 and 3 had no voltage and the rest of the pins had 0.25 to 0.3 volts. So my question is what voltage should I be seeing when testing the pins for voltage with a multimeter?

    The USB 3.0 header on the Acer Aspire ATC-710-EB51 typically follows the standard pinout for USB 3.0 headers. Here are the voltages for each pin:

    Pin 1 (Vbus): +5V
    Pin 2 (D-): Data line, typically 0V to 3.3V
    Pin 3 (D+): Data line, typically 0V to 3.3V
    Pin 4 (GND): Ground
    Pin 5 (StdA_SSRX-): SuperSpeed receiver, typically 0V to 3.3V
    Pin 6 (StdA_SSRX+): SuperSpeed receiver, typically 0V to 3.3V
    Pin 7 (GND): Ground
    Pin 8 (StdA_SSTX-): SuperSpeed transmitter, typically 0V to 3.3V
    Pin 9 (StdA_SSTX+): SuperSpeed transmitter, typically 0V to 3.3V

    Delete your driver and re-install or update the driver software.

    Other than that look for broken twisted pins in all USB Ports as others can affect all of them.

    There are 19 pins in this USB header, which is what the 3.0 version has

    I’ve tried uninstalling and reinstalling the drivers and they’re all up to date. None of the pins seem to have any damage, as you can see in this picture:

    You might do a recover or reset in System Settings.

    Just be careful to not wipe your data just go to System Settings < recovery
