[Thunder3 Duo Pro] Can I use both the Thunderbolt and the USB interface at the same time?
The AKiTiO Thunder3 Duo Pro has both Thunderbolt 3 (USB-C) ports and a USB (Type B) port. However, you can only connect one of these interfaces to the computer at any given time. It's not possible to use both simultaneously (when one interface is in use, the other port is disabled). When the device is connected to the computer via Thunderbolt 3, additional devices can be connected to the second Thunderbolt 3 (USB-C) port in a daisy chain but not to the regular Type B port.
