    A USB from my laptop has stopped working.

    Hello, I have a laptop PC ASUS2013 S200E-CT182H that a USB port has stopped working. Power arrives, but does not recognize any device connected to it.
    I looked in Device Manager and there was a USB connection that said:
    Unknown USB device (Device descriptor request error)
    and in the properties of the USB it appeared this: Windows stopped this device because it reported problems. (Code 43)
    I uninstalled the connection so that when I rebooted it, windows 8.1 reinstalled it. Now I do not get the error, but the connection still does not work. If I connect a pendrive with LED or a hub with LED, the LED turns on, but it does not work. Does not recognize the device.
    I have uninstalled all the drivers of the serial bus and it remains the same.

    regards!!!

    Re: A USB from my laptop has stopped working.

    You said "a" USB port. Does that mean other USB ports are still working?

    The fact you see power to the LEDs just indicates the presence of +5VDC. It does not mean there is the necessary data connection. There typically are one or more USB "hubs" integrated with the motherboard.

    While you have done some of these, you might run through this again and note Method 3. Disable Fast Startup.

    Re: A USB from my laptop has stopped working.

    Thanks @digerati. The computer has the left side of two USB's, a USB 3.0 that works correctly and a USB 2.0 which is the one that does not work. On the right side there is another USB 2.0 that also works correctly.
    sorry, but I do not know what means "Method 3". I have dissable Fast Startup.

    Re: A USB from my laptop has stopped working.

    Sorry! My mistake. In my last post, "some of these" was supposed to be a link to some things to try. Method 3 was to disable Fast Startup. Since you did that and the other suggested items, no need to include the link now.

    Since it appears you no longer see errors in Device Manager and your other USB ports work, I don't know what more you can do without disassembling the notebook and looking for loose connections, cold solder joints, or broken wires. And since opening up a notebook is tricky and can result is more loose connections or collateral damage, and since you have several other working ports, I recommend you just remember to avoid using that bad port. Since it still has power, you can always use it as your cell phone charging port.

    Thanks @digerati. I think it's impossible that it could be a physical thing. The computer does not move, I use it as a desktop. It's difficult for a cable to be disconnected.

    Re: A USB from my laptop has stopped working.

    The fact it does not move does limit the possibilities a cable came loose. But it does not eliminate the possibility. If it was a little loose in the first place, any vibration from footfalls, opening and closing the lid, banging the table, etc. could eventually cause it to come completely loose. Even the expansion/contraction properties of matter during heat/cool cycles can do this. But you are right, it is not likely. But a cold solder joint can and often does eventually go bad. Or perhaps the connector got damaged when a cable was plugged in. It is impossible to tell for sure.

    Re: A USB from my laptop has stopped working.

    I'd need a laptop with 3 working USB ports. (My mouse always takes up one port and I have a DVD burner that uses a Y power connector which uses the other 2 ports at times.) Since you have 2 that work and you mentioned the laptop is used like a desktop computer, you might want to use this workaround. Buy a powered USB hub with 4 or more ports and plug it into the functioning USB 2 port. You'd then have a total of 5 or more working USB ports. (make sure the hub says USB 2 because some peripherals don't like USB 3 yet)

    A powered USB hub is one that has a power brick with it. If you use one that supplies its own power, you will not be damaging the USB port that the hub is plugged into by trying to get more power than it can supply.

    I have loaded linux live with a USB and I tested the port. It does not work either. Then it is confirmed that it is a physical fault. Thanks @Digetari

    ...and thanks for your advice @plodr
