Using HTC VIVE Facial Tracker with non-HTC HMD

[Contra_Shark]

I'd like to use the VIVE Facial Tracker with my WMR headset. I've found a 3D print to mount the facial tracker to the headset. However, I'll need an extension cable to connect the facial tracker to a USB port on my PC. It'll need to be at least 5m long. To ensure that I buy a compatible cable, could I have the specifications? I'm specifically looking for the required speed (e.g., USB 3.0) and power (e.g., 900 mA, 5 V, 4.5 W). How much power (current and voltage) does the facial tracker draw?
