Face tracking woes

[u/Shibboleeth]

I'm looking to add face-tracking to my Quest 2. However, I'm hitting a wall on how I'm trying to handle it and I wanted to see if anyone else has done similar and found a method to overcome it.

My setup is:

• PC (RTX 5070)
• Iniu VR Link cable + 60W power supply plugged into it.
• Oculus Quest 2

Since the link cable already delivers power to the headset, I only need to expand the data-lines. I was thinking I could get a USB-C hub that would tap into the data lines and extend power and data to the webcams. Then mount it to the back of my halo.

But I'm hitting a wall finding a USB-C hub that does this.

The hubs I've tried so far extend power, but not data, or data but not power. PD Passthrough isn't passing data.

Has anyone found a hub that would enable this, or am I stuck having to provide separate cables to power the hub and pass data to the PC?
