Problem:
RX3 and Rekordbox Pro Dj LINK mode (via USB) does not work.
The LINK button will show in the Rekordbox, after clicking it will be active (LINK 1) but the player will not be connected, the music / lists cannot be browsed (not visible).
Only the controller / MIDI mode connection option appears in the RX3 Source list. For the last 3 weeks there has been no bug, it has worked.
Details:
PC: i5 9600, 32GB
WIN 10 Pro, version: 21H1
Rekord box version: 6.6.1. (but the same bug with all previous versions (I didn't uninstall previous versions))
USB Connection (Link Export) driver for Windows10: 10039.20_07242020 (already Uninstall then Install done)
Firewall rules (in WIN Defender): all passed, all rekordbox versions and other Pioneer add-ons. Also for public and private networks (but I use private network mode). I also turned off the firewall as a test, but it didn't solve the problem.
There is no other internal firewall on the computer.
I tried to replace the USB cable (2 others brand new).
I tried to use a different USB port (both front and back).
I also have an XDJ-RX2, there is a problem with that as well. (I've been using it for years without any problems).
I have noticed that after connecting the universal (virtual) network adapter (via USB), the player does not have an IP address. It's like DHCP doesn't work, but unfortunately I don't know how to get an address.
I tried to give it a manual IPV4 address, but there was no solution.
The player works properly in controller / MIDI mode (Performance) and connects to the Recordbox. LINK alone doesn't work.
I assume that a Windows update component may be causing the current USB LINK driver. But unfortunately I did not find any information on this. This is just a hint.
I'm an IT professional, any extra data needed to collaborate, I'm happy to help!
Help Obi Van Kenobi, you are my last hope!
