I selected all and copy/paste before it popped up with the subscribe. It's not perfect and I didn't do any editing, but it's readable.

Edit: now that I read it, I guess it's not all there but TLDR there is encryption between the dock and console that prevents 3rd party docks.

How Nintendo locked down the Switch 2’s USB-C port and broke third-party docking

We whipped out a USB-C PD analyzer to test how Nintendo walled its garden this time around. by Sean Hollister Jul 2, 2025, 3:47 PM EDT

There’s always a reason why universal USB-C ports don’t “just work” like you’d expect. In the early days, it was incompetence or naiveté. Later, manufacturers often cheaped out. But in the case of Nintendo’s Switch 2, it appears to be intentional.

With the Nintendo Switch 2, it should be easy to plug your new, more expensive console into video glasses or TVs when you’re traveling away from home. USB-C makes it so. But Nintendo has intentionally broken the Switch 2’s compatibility with those devices, using a new encryption scheme and some form of dedicated encryption chip, two accessory manufacturers tell The Verge.

I haven’t yet found proof of that encryption chip myself — but when I analyzed the USB-C PD traffic with a Power-Z tester, I could clearly see the new Nintendo Switch not behaving like a good USB citizen should.

If you’ve been wondering why there are basically no portable Switch 2 docks on the market, this is the reason. Even Jsaux, the company that built its reputation by beating the Steam Deck dock to market, tells us it’s paused its plans to build a Switch 2 dock because of Nintendo’s actions. It’s not simply because the Switch 2 now requires more voltage, as was previously reported; it’s that Nintendo has made things even more difficult this generation. How docking works

That “U” in USB isn’t always “universal,” but this is generally true: if you plug any USB-C to HDMI adapter, dock, or hub into a USB-C laptop, tablet or handheld that supports USB-C video output, you can expect to see your screen automatically appear on your TV.

The magic is normally possible because of a simple, standardized set of instructions that any manufacturer can follow to make their docking station or hub “talk” to the computer.
