I just got the Besavious U5 and I cannot get it to work with my PS5 and a XIM Apex. I have tried using the supplimentary power cable and without it and the XIM will simply not connect to the PS5. I have the PS5 Dualsence controller connected to the side port on the U5 and have the XIM Apex connected through the rear USB slot. The XIM APex just flashes and will not initialize. I'm using an Xbox One S controller and if I remove the XIM Apex the controller will work fine but obviously I cannot use mouse and keyboard this way.
I know the XIM Apex works fine becasue I use it on my Xbox Series S without issue and it connects and lets me use M&K in my games.
Wow, that actually worked. I plugged the XIM Apex into the Besaviour U5 and the dusense into the XIM hub and it initialized no Xbox controller needed! Thanks!
