Yes, You can connect either of the RØDECaster Video, RØDECaster Pro II or RØDECaster Duo's USB ports to your RØDE Hub for communication with your computer.
You cannot, however, use the RØDE Hub to add extra USB ports on the RØDECaster, since it will block communication between the RØDECaster and your accessories.
For this reason, you need to connect external USB devices, such as a mobile phone or compatible USB Microphone, directly to the RØDECaster's USB ports.
For more information on the RØDE Hub, please see our RØDE Hub User Guide
