Hobbyist patches €40 USB-C hub’s firmware to work as a Nintendo Switch 2 dock
A hobbyist has successfully turned a $45 USB-C hub into a functional Nintendo Switch 2 dock by modifying its firmware with just 540 bytes of code.
The modified hub responds to Nintendo's vendor messages with the same identity as an official dock, enabling TV mode functionality that wasn't available with the stock firmware. Additionally, a separate firmware fix corrects washed-out HDR output over HDMI.
Proprietary Solution
The modder noted that "Nintendo went in a proprietary direction (as they so often do)," which necessitated the firmware modification. The project was undertaken specifically to create a more portable travel dock alternative to Nintendo's official solution.

Practical Benefits
The modification comes at no noticeable cost, as the hub continues to function normally with other devices like PCs and phones. This clever workaround demonstrates how enthusiasts can overcome manufacturer restrictions to create more versatile solutions.
