What Does the Blue LED Light Inside the Adapter Indicate?

When the adapter is connected to a PC, the blue LED lights up when the PC communicates with it, showing the adapter is physically connected and responding to the PC.

The light should come on, at least momentarily, even before drivers are installed. If the light does not come on, try a different port or rebooting the machine. If this does not help, please contact us at support@plugable.com.
