Nintendo Locks Down Switch 2 USB-C Port: Breaking Third-Party Dock Compatibility with Proprietary Encryption

According to a report by The Verge, Nintendo has implemented a proprietary encryption mechanism and specialized chip design in the USB-C port of the forthcoming Nintendo Switch 2, effectively limiting compatibility with third-party accessories. As a result, players are unable to use docking stations, expansion hubs, or adapters produced by non-official manufacturers.

The report reveals that Nintendo has introduced a dedicated authentication process for the USB-C port on the Nintendo Switch 2, including additional encryption layers that deviate from the standard USB-C specifications. This proprietary configuration renders common USB-C to HDMI adapters inoperable and disables previously functional third-party docks designed for the original Nintendo Switch. This strategic move appears intended to further entrench Nintendo’s peripheral ecosystem and enforce certification for all Switch 2-compatible third-party accessories.

Due to this restrictive design, third-party manufacturers such as Jsaux have found their planned Nintendo Switch 2 expansion products incompatible with the new console, forcing them to delay product launches indefinitely.

While the USB Implementers Forum (USB-IF) stipulates that USB-C ports adhering to open standards should support DisplayPort Alternate Mode and USB Power Delivery (USB-C PD), Nintendo has clearly constrained the USB-C functionalities on the Switch 2 to only operate with its own official or licensed peripherals.

Consequently, users wishing to utilize docks, hubs, or adapters with the Nintendo Switch 2 must now purchase either Nintendo-branded products or accessories certified by the company. Previously compatible third-party accessories designed for the original Switch may no longer function as intended with the new device.
