Indicator LED details
The color and action of the indicator LED depends on whether you are connected by USB 3.0 or USB 2.0. For
maximum performance, always use a USB 3.0 port and the included USB 3.0 cable. Note that frame capture rate
will be reduced when connected via USB 2.0.
If you’re not sure if your controller is USB 3.0 or USB 2.0, plug AV.io HD into the capture computer and look at
the indicator LED:
A solid blue LED means USB 3.0 and… a solid green LED means USB 2.0
