It is still just using regular USB-C. I took inspiration from https://www.youtube.com/watch?v=Btwqt-w85Vk and used a similar cable to connect other devices of mine to the Switch 2 dock and they just work. Switch 2 seems to check the hardware ID. I’m sure if there is some kind of way to fake the hardware ID, Switch 2 would just work with other docks as well.
I can later do an “lsusb” command on Linux using the dock2 and read its hardware ID. The one I currenty use just says xxxxxxxx USB Type-C Digital AV Adapter
