I have zero (0) USB devices attached to my Mac Studio. Yet in the System information this shows up. What is it?
Mac Studio, macOS 13.1
That doesn’t make any sense to me.

USB-C can support various different connections, but an individual USB-C connection probably won’t support everything that can be connected. That particular billboard component is part of the internal USB-C xHCI hardware, and deals with alternate mode operations. That component provides data that can be displayed to the user when some incompatible USB-C device is connected.
here is my similar readout from an older Mac Pro 5,1:

Could be Bluetooth or Wi-Fi module.
Thank you. I tried looking it up on line but quite a lot of the answers dealt with Windows. Even when all my peripherals are connected there is nothing attached to it.
TL;DR: Billboard is a hunk of the USB-C specs.
USB 2.0 BILLBOARD - what is this?
