How To Fix USB Stops Working Issues In Windows

Does your computer’s USB stops working? If you are experiencing problems with your USB devices, there are a couple of things you can do to try and resolve them. Most new computer components, such as printers, keyboards and mice, scanners and digital cameras all interface with your computer via USB. USB is a technology that allows devices to be hot-swapped, which means you can generally disconnect it without having to power down the computer. Occasionally, however, you might experience problems with USB devices not being recognized or shutting down unexpectedly.

USB Devices Not Recognized

If you are trying to plug a device in but it is not showing up, make sure the device is plugged in and powered on (if necessary). If you have multiple USB ports on the computer and other devices are working, try the problem device in a known working port. If it works in the other port, you may have a bad USB hub. You can try uninstalling the hub in the Device Manager and then rebooting the machine. Windows will find it again and install the necessary software drivers. This will often fix the problem.

If you successfully connect a device via USB, but the USB stops working after a while, you will need to edit the power management for that particular hub. Right-click My Computer, select Properties, then Hardware and then Device Manager.
