6.2.2 Important Information When Connecting USB Devices

When connecting a USB device, read the following important information.

USB 3.0 Support

When using NintendoSDK NX Add-On version 1.1.0 and later, USB 3.0 is not supported. Even devices that support USB 3.0 have the same behavior as USB 2.0 devices.

While devices that support USB 3.0 can be used with earlier versions of the SDK, operation is not assured.

Connecting Devices That Support USB 3.0

Connecting some devices that support USB 3.0 may affect 2.4 GHz communication.

The following problems may occur.

Item Symptom
Wireless communication with controllers
  • Connection failure or disconnection
  • Delay or error in applying input
Local Communication
  • Communication partner not found
  • Loss of socket communication
2.4 GHz wireless LAN communication
  • Connection failure or disconnection
  • Loss of socket communication
  • Communication delay or slower speed

If these kinds of problems occur, try the following.

  • Move the USB device as far from the console as possible.
  • Plug the USB device into a USB port that supports USB 2.0.
    (This step provides performance equivalent to USB 2.0.)
  • Replace the USB device with one that does not support USB 3.0.
  • Use a 5 GHz wireless LAN.
    (The effect on local communication between ADEV consoles or wireless controller communication will not be improved.)
Info

These problems occur due to the nature of USB 3.0 devices. The same problems occur with the Switch retail product.

Connecting a USB-Ethernet Adapter

The following operations are not supported.

  • Detaching and reattaching the USB-Ethernet adapter to the Nintendo Switch dock while the ADEV remains turned on
  • Connecting multiple USB-Ethernet adapters

If the ADEV system stops working due to these operations, restart the ADEV.
For more information about restarting the ADEV, see 8.1 Restarting the ADEV.
