If you haven't tried, try connecting the USB dongle to a different USB port and check if it fixes the issue. If the issue persist, connect the dongle to the port, go to device manager and uninstall all the USB drivers. Then, restart the computer to reinstall the driver (make sure that the dongle is still connected):
Step 1: Connect the USB dongle. Check if the device is getting detected under Device Manager.
Step 2: Press Windows + X keys and select Device Manager.
Step 3: Right Click on all the USB devices and select Uninstall.
Step 4: Restart the computer, and Windows will reinstall all the USB drivers.
I would also suggest you to update the latest driver for the USB Dongle from manufacturer website.
