Nothing happens when I connect rekordbox for iOS (ver. 4) to the USB terminal of a CDJ/XDJ/DJM.

In rekordbox for iOS (ver. 3 or later), the process for making a wired connection has changed from the previous method of connecting from a USB Type-A terminal to a USB Type-B or Type-C terminal.
To learn how to connect, click here.
Traditional connection methods limit file transfer speed, and file formats such as WAV/AIFF and FLAC/ALAC can’t be used.
With rekordbox for iOS (ver. 3 or later), we've changed the wired connection method to allow these file formats, and to improve stability.
