The USB receiver (Dongle) is unstable or doesn't work when plugged into a USB hub / extension port / monitor USB port. What should I do?

If the receiver is unstable when plugged into an extension port, USB hub, or a monitor's USB port, we recommend plugging it directly into the computer's own USB port and trying again.
If it still doesn't work when plugged directly into the computer, try a different port; if it still fails, please contact official customer service.
