This is an ideal setup for me! Does it really work? It looks to me like you're doing PCVR wired streaming over ethernet (?!?!) with power delivery via USB-C (the red cable in your image) and a little USB-C female-to-female adapter to connect the hub to the XR Elite Pro in glasses mode. Is the Sandisk flash drive doing anything there?
I've been desperate to get a wired PCVR streaming setup on my computer, which doesn't have a USB-C 3.2 Gen 2x2 (USB-C 20Gbps) port but does have a spare USB-C 3.1 Gen 2 (USB-C 10 Gbps) and a spare ethernet. I'd be happy to power the hub with an AC wall adapter instead of the power brick. I just need the wired PCVR in glasses mode!
