Hi Baddielaz, I'm using a very similar usb switch with my Apex but Usb 3.0 (see below link),. Upgraded to Apex beta firmware so I can play PS5 games. Setup is; one of the usb input leads plugs into the Apex fob\dongle and the other into my pc, keyboard - mouse & controller plugs into the front of the output usb's (the usb hub that comes with the Xim is not used at all). Everything works perfect, only thing I have to do is unplug the Controller when switching and using my pc because it plays havoc with Google Chrome (stops responding ) for some reason.
