> The inability for most docks to support the Switch 2 may not be malicious from Nintendo. It might just be a poor or lazy implementation of the USB-C specification
From the verge [0], 2 months ago:
> When I analyze the conversation between the Nintendo Switch 2 and its dock, I can see the two devices begin speaking in Nintendo’s own flavor of “vendor defined” language early in the conversation, before they sign off on any video output. And then, seemingly before the dock confirms that it’s engaged video-out, they send over 30 proprietary “unstructured” messages to one another.

> According to Antank, which says it checked with its chip supplier, that hexadecimal string “is indeed the current key being used by Nintendo.” My other sources are less sure.
I'm pretty sure lttl's conclusion is plain wrong. It is not JUST lazy USB-C implementation, but a purposefully designed special proprietary protocol on top of USB-C
