The ADEV may need to be connected to a PC when installing applications or writing to an NX development card.
The Relay Box-A is used to connect the ADEV to a PC.
The following actions are not supported while the ADEV is connected to the Relay Box-A because it is normally in TV mode.
To operate the ADEV while it is connected to a PC, connect the ADEV to a TV and use a detached Joy-Con, or switch the ADEV to handheld mode.
For more information about switching to handheld mode, see 8.4 Switching Between Handheld and TV Modes.
If the ADEV is attached to the Nintendo Switch dock and the dock is connected to the Relay Box-A, the PC cannot recognize the ADEV. Remove the ADEV from the Nintendo Switch dock and connect it directly to the Relay Box-A.
You cannot use connected USB devices regardless of whether the Relay Box-A is connected to a PC.
