Having trouble with a device? Make sure everything is connected properly, the device has power, and that it’s set up correctly.
First, try checking your hardware
- Unplug USB cables and wait for a little while for the device driver to be unloaded by Windows, and then plug the device back in.
- Try using a different USB port on your PC.
- If you use a USB hub between the device and the PC, make sure the hub has power. If it’s still not working, try removing the USB hub and plugging the device directly into a USB port on the PC.
- Make sure that the cables on your device aren't damaged in any way.
- Check any battery-powered devices to see if they are fully charged or have fresh batteries.
- Make sure there’s no dirt blocking keys or sensors.
Check your wireless connections
- Look on the bottom of the wireless device for a Reset button. Resetting the device will disconnect and then reconnect the wireless connection. There might also be a Reset button on the USB receiver for your device.
- For USB wireless devices, this might be as simple as unplugging the USB wireless receiver, waiting for about 10 seconds, and then plugging the USB wireless receiver back into the USB port. The wireless connection should be reestablished.
Check the device
Some devices won't work without installing a driver. When testing the device on another PC, make sure that you have the correct driver installed for the device.
