Supported USB LED Devices

Any 5V single-light USB LED device is supported. The program controlling the LED is generic and only controls the voltage supplied to the USB port.

The IOX-WRKS device can light up any LED lamp attached to the USB Host wire of its wiring harness.


I don’t see any light at all, and I expect to.

It will be one of these scenarios:

  1. There might be no power getting to the IOX-WRKS. If there are no lights on the GO device, fix that first. Only after all 3 lights are on the GO: red, green, and blue, does the IOX-WRKS function. If that is ok, then
  2. Unplug the Mini-USB cable from the GO device, then plug back in again and make sure it is seated well. It also helps to wrap a zip strap tie around it. If that doesn’t fix it, then
  3. The USB LED Light itself might be faulty. Try replacing your USB LED lamp with a different one. Also, the Dollar Store has USB charging cables that light up. Those ones seem to be more reliable than the little reading lights.
  4. If needed, replace the cable coming from the IOX-WRKS, with a new one, that plugs into the GO device.
  5. If nothing above works, then you might need a new IOX-WRKS device.
