Oculus rift S Orange light issue Fixed

[Grandad Druce]

Hi CMDRs,

I was having an issue quite often when before playing a VR game including ED my Rift S would have an orange light in the headset and it would show disconnected in the Oculus software. The only way to fix it was to replug the USB 3 lead and then it would be ok. Scanning the web it seems like this is a common problem without apparent resolution even from Oculus. I put my thinking cap on and wondered if the two USB 3 ports (stacked directly on my mobo) had a priority order. I had my mouse plugged into the first (lower port) and the headset into the second. I thought that the mouse might be interfering with the Rift(as its the first thing that's used once the pc is fired up). I swapped the leads around and.... hey presto no more orange light! just wondered if I should let Oculus know somehow as they have been bombarded with emails for a few years over this by several Rift users.

Going to try using the SRV in VR for the first time tomorrow. Sick bag in the seat pocket ready!

Cheers, GD

No point reporting it. Oculus will not be interested. They already offer the blunderbus suggestions such as 'trying another USB port' etc... Whilst great (in a 'bang for buck' context) most of the time, the Oculus software and drivers are poor in handling these conditions, and often need the cables re-connecting to resolve these oddities.

Port "priority"? No (not really). "Dependencies"? Yes.... "Other factors" yes..

There isn't a formal priority for usb ports, but there are interrelationships between ports. Particularly those right next to each other (No gap) USB ports are commonly paired togehter with a pair of ports controlled by the same chip within the PC and sharing power to be supplied to the connected device. If you have enough USB3 ports, mybe also leave the port paired woth the one that the rift is connected to free... If you have enough PC skills to use Windows device manager, also try disabling the option to allow Windows to tiun off the device to save power (it will be on some of the USB hub device propertied somewhere. This varies between PCs so I can't be more specific..

If your PC has USB2 as well as USB3 connections. Use the USB2 power for things like Mice, Keyboard. As mentioned above, leave the port 'paired' with the Rift empty if you can...

The Rift does squeeze a lot out of USB3, and its error condition handling could be better. Add to this the USB3 driver and hardware on PCs commonly being quite quirky, you often have to end up doing a port juggling act to find the combination that works for you, as you found out.

I've also found stopping and restarting the Windows service "Oculus VR Runtime Service" (OVRService*) that controls the Rift) to fix some issues, and in other cases the Rift reporting display port connection problems that are not fixed by reconnecting the DP connection, but are fixed by replugging the USB!!!!.

For completeness (mainly for anyone else stumbling over this post) - Avoid using extension cables with the Rift - if no choice, use as short cables as you can and expect issues. I have to use short extension cables and barely get away with 1ft leads.... Do not use USB hubs to drive the Rift (powered or otherwise). Snow on ED loading screen? - try reseating the display port lead.

( * -I actually have batch files to control whether the Oculus service is running on my PC at a particular instant. "net start OVRService" and "net stop OVRService" turn it on and off as required)
