In software update 1.3.1 of the Huddly IQ, it was introduced support for streaming from Huddly IQ through Crestron Mercury over USB 2.0.

This update allows for USB 2.0 mode to be used on this particular setup (Crestron Mercury), and the Huddly IQ requires a USB 3.0 connection to get enough power to run the extra features, such as Genius Framing. 

In order to make the USB 2.0 mode work with Crestron Mercury, the only recommendation is to use a power injector provided by Crestron, which is supplied for this purpose: Anker USB hub
Other extenders are not certified for this particular setup.

USB 2.0 mode on the Huddly IQ might work on other USB 2.0 setups, but this is not something we can guarantee, nor do support on at this stage.
If you Huddly IQ is experiencing any problems, please make sure to test it with a USB 3.0 port.
