The Mystery of Webcam Compatibility with Nintendo Switch 2 Solved: Update Coming Soon

The compatibility issue of webcams with Nintendo Switch 2 has finally been addressed, and a firmware update is in the works. If you connect the top-rated models today, they may not function, while older cameras work without issues. Why is this? It remained a mystery for almost three weeks after the console's launch. Now, two companies have announced that they have figured out the problem and are preparing updates for their cameras.

The simplified answer is that modern powerful webcams support many modes via USB, but the Nintendo Switch 2 selects modes that not all cameras can handle correctly. For example, Elgato added a low-resolution 480p mode for its Facecam MK.2 and Facecam Neo models. Elgato's CEO, Julian Fest, suggests that the Switch may only support "very low resolution" for displaying multiple cameras on the screen simultaneously.

However, low resolution is not the only factor. The official Nintendo Switch 2 camera has a resolution of 1080p and broadcasts in this mode (we have verified this). Additionally, not all cameras with 1080p support or higher work with the console.

Ugreen informed The Verge that the technical requirements for a camera to work with the Switch are more complex than just resolution or frame rate. Ugreen representative, Gabriel Wanga, explained that the camera must avoid modes or protocols that the Switch may not recognize or support. According to her, three conditions must be met for compatibility with the console:

• The camera must not use the HID protocol.
• It must operate in isochronous data transfer mode, not Bulk, which is more resource-intensive.
• The USB descriptor must not support low frame rate modes (below 30 fps).

These parameters are usually not listed on the packaging, but they can be checked using a PC and the USBView tool. For example, Elgato's Facecam MK.2 supports isochronous mode and does not use the HID interface, but it may violate the third condition, as its operating frequency can be up to 5 fps at various resolutions. If the hardware cannot support these modes, the camera may not work with Switch 2.

In this context, Ugreen had an advantage—some of its models worked with the console, while others did not. They promise to release updates for models CM826 / 55512, CM797 / 45644, and CM825 / 75330 by the end of June. Meanwhile, models CM678 / 15728, CM778 / 35626, CM717 / 25442, CM825 / 55721, and CM831 / 65381 are already compatible with the console.

It is worth noting that the responsibility for compatibility does not solely lie with the camera manufacturers. PCs typically do not have such issues with video modes. Perhaps Nintendo will rectify the situation with a system update. As of now, Nintendo has not commented on this issue.
