Won't Recognize Usb Connected Device

Below some tips you can do to fix that problem

So how did I finally fix the problem? Well, if you are lucky, it's a super simple solution! Try this method first and if it works, you'll have saved a lot of time.

Simply unplug your computer from the power supply. Yes that is it! Note that this does not mean just turning off your computer using the power button because most modern computers don't actually turn off completely and the motherboard will still get power. This is useful sometimes if you want to remotely wake up a computer, etc.

If Windows is not able to recognize the device, you may also see in Device Manager that the device shows up as an "Unknown Device". You can get to Device Manager by clicking on Start and typing in devmgmt.msc or by going to Control Panel and clicking on Device Manager. In that case, you should right-click on Unknown Device, click on Properties, then the Driver tab and then click Update Driver.

The next thing you can try is to disconnect all USB devices and then restart the machine. once you have restarted, try to connect the USB device that was causing the problem.

If that particular USB port doesn't recognize it, try another one. If the device is recognized by a different USB port, there could be a hardware problem with one of the USB ports. If no USB port recognizes the device, then keep reading because it's probably something else.
