My issue is, I can't get the Titan one to function through my VenomX attached controllers like when using a mouse or other attachment (keyboard etc). I am using The VenomX mouse, and the ps4 controller combination. In my case, I have found that the Titan one does not function with the controller which is being authenticated through VenomX(yellow light). I have also tried PC setting which did not help. I also tried plugging the VenomX directly into the Titan and the Titan to the ps4, this did not work. Plugging the titan one into one of the 3 VenomX ports, also did not work
If you could double check to see if this is the same for you that would help, i'm pretty sure its not compatible in that way.
*note: The titan wont even do anything if you just plug it into the venomX with the dualshock4 as normal. You have to switch around users/controllers and then you can "trick" the Titan into authenticating, and running through the VenomX, but its running with a Blue led, meaning no other extra controllers are working.
