The receiver cannot be recognized by the computer (QM-PR1)

Please check the following.

• Make sure there are no problems with the USB cable.
• Make sure the USB connectors on the PC and receiver are inserted all the way.
  The USB connector may not be inserted all the way.
• Make sure you are using the included USB cable.
  If you are using a different cable, it may not work properly.
• If you are using a USB hub, unplug and plug in the USB between the PC and hub.
  We have confirmed that a problem with the hub causes the Windows device driver to not recognize the device.
  (We do not recommend using a USB hub.)
