Meta Quest 3S haptics hub and audio requirements

Useful Answer

Meta Quest 3S has a single USB-C port and no built-in 3.5mm audio jack, so using the X-Arcade Gen 2 dongle and wired haptics audio at the same time requires a hub/adapter.

The hub needs to support:

• USB data for the X-Arcade wireless dongle.
• 3.5mm audio output for the haptics kit audio cable.
• Charging/power passthrough if the customer also wants to use an external battery or keep the headset powered.

Not all USB-C audio adapters or hubs pass both data and power correctly. A hub can work for audio and dongle data while still failing to pass external battery power through to the headset.

Support had confirmed one hub as working for Gen 2 dongle + audio cable use:

A later customer confirmed that this larger hub solved the Quest 3S setup after a smaller adapter passed audio but did not keep the dongle connected. If a hub gives sound but the dongle disappears, it is likely audio-only or charging-focused rather than full data + audio.

The yellow adhesive on PCB connectors is a manufacturing aid to secure connections during shipping and vibration. It is not required for normal operation after a PCB swap, though loose connectors should still be fully seated.

Source Context

The customer reported that a simple USB-C to 3.5mm adapter did not solve the Quest 3S haptics audio setup, and that one hub did not pass backup battery power through to the headset. Support identified data + charging passthrough as the missing compatibility requirement. A later Quest 3S customer confirmed the recommended larger hub worked because it preserved both 3.5mm audio and dongle data.
