I believe the port nearest the HDMI is the analogue audio out, the port near the edge of the Vero 4K is for the IR receiver.
I don’t think the IR receiver really replaces the USB dongle as USB dongle is radio rather than IR, the IR receiver will allow you to use those all-in-one learning remotes.
From the quick start guide
Please note that the IR extension kit is only recommended if you are using a remote other than the OSMC remote. The OSMC remote does not require line of sight as it uses radio frequency instead of infrared.
The IR receiver is only of use if you plan on using an IR remote control. The IR receiver should be plugged into the 3.5mm port on the outside of the Vero 4K (NOT the one near the HDMI port).
If you wish to use the OSMC RF remote control that was bundled with your Vero 4K then you don’t need to use the IR receiver at all and you can just leave this disconnected (Most people will use their Vero 4K like this), in this scenario you will need to use the USB RF dongle (Plugged into either USB port).
The IR extender kit is for those that want to use an infrared remote and mount the device behind the TV. Vero 4K features a built in IR receiver, but this requires good line of sight (as is the nature of IR).
The kit is not a substitute for RF: but we understand that some people may want to use a universal remote control instead of having another remote.
USB ports are functionally the same in their current configuration but can be adapted for OTG, hence the different colour marking.
If you’re putting the device behind the TV, you will want the IR extender kit. No RF module necessary.
But if your TV is modern it should support CEC, meaning IR isn’t necessary. Using IR for this remote would send duplicate signals and require you to record key presses to create an appropriate configuration file
@sam_nazarko, I still don’t understand why the colours are different if they can both be adapted for OTG. Or is it just the white one that has this capability?
(Sorry for necroing this thread…)
Also, can you please confirm which of the two jacks is for audio, and which for the IR receiver?
Is there a reason none of these ports are labelled or colour coded? I feel the Vero 4K is perfect in so many ways, but this is poor design.
