We occasionally hear from people that their IR light bar does not appear to work.
Symptom: They plug the IR Lightbar into the iWavit USB dongle and plug the USB dongle into a USB socket.
The USB light blinks 4 times, as it should, but the red LED on the IR light bar does not light up, and any subsequent IR blasting does not work.
Resolution: When you plug in the IR lightbar plug into the side of the iWavit USB dongle, please make sure that you hear the "snap". Otherwise it is not plugged in all the way. So far this has accounted for 100% of the reported failures.
