If your USB keeps disconnecting and reconnecting after you connect your USB device on its own randomly, then the problem might have something to do with a hardware or driver issue. The first thing you have to do in such a case is to make sure that the device is working on another computer. This will help you isolate the problem and if it turns out that it works, then the problem lies in your computer and not your USB device.
To fix this connection problem between your USB device and Windows 10 computer, you can use the options given below as a reference.
Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.
You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.
You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.
If you were unable to install the Universal Serial Bus controller drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:
Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.
