ARC-8050T3U includes one Thunderbolt 3 active cable and one USB Type C cable in the shipping package. The currently Thunderbolt 3 active cable based on Cooper Bridge only supports Thunderbolt 3 and USB 2.0 protocol. You need to use the USB 3.2 cable with the USB Type C to type A adapter to get the real USB host performance. In the future new 1-2m TBT 40Gbps Thunderbolt™ 3 cable based on Delta Bridge (new Re-timer) will be updated to support Thunderbolt, USB, DP for increasing cable length.
