Sudden loss of all input peripherals including keyboard and mouse

[tvcasualty]

This happens to me with the Aero and a RTX 4090 (VR) all the time in the 262 as I aggressively track the enemy using my head.  It suddenly locks out everything and all I can do is watch as I crash and then must restart the game.

Been a while since I got to play but same thing happened again today.  Its not a USB disconnect issue as the devices function fine outside of the game while the plan death spirals in the app behind.

It got me thinking is everyone thats had this beenusing SteamVR like myself or are others getting it still when using OpenComposite?

[spreckair]

I am using SteamVR and have not had this issue for quite a while now.  I think the thing that did it for me was updating my BIOS (ASUS) and running the Windows system file checker.  Also, I ditched the USB hub I was using and connected everything directly.  Best of luck to you.

It can be just a very short disconnect, like half a second or so, so if it works in Windows after that, it doesn't mean a thing.

Same happened to me twice this week, Quest 3 with OpenComposite, lost all input in game, including keyboard and mouse. Had to use VR menu (virtual desktop menu) to kill the game. All USB working fine outside of game.

Two times on this month this happend to me on Combat Box in the Middle of a dogfight, screen freezes, sound keeps going and all periferals including mouse and keyboard stuck. 

 

Im using Reberb G2 and OpenXr with Opemcomposite.

This has become a major (everyday) issue lately  (the past week).

After I press 'start' on a mission, the mouse stops working or trackir or CH Products or all of them together.

 

 

I also suspect issues might happen after Windows updates. (I've had this problem in the past).

 

I plug all my usb devices into MB connections; no hubs.

I also have this issue using Pimax Crystal and OpenXR. Makes it essentially impossible to play as it is frequent.

I had the same issue for a long time, specifically the one where everything stops responding and also the view gets stuck when you look over your shoulder. 
This is the fix:

Jay @jay2cent put up this vid https://www.youtube.com/watch?v=YWTZkB9rVU0 showing how to possibly deal with the problem. He explains at the last 5 - 6 minutes of the vid what he saw happen and how it was fixed. Hope you get help from his findings.

In that video though he's talking about stuttering and USB device disconnects (ie you hear the disconnect sound, or reconnect sound etc).

 

In this issue's case with IL2, neither of those are a problem. E.g. my computer is running perfectly fine, there is no stuttering, and none of my devices disconnect from windows.
I do have that sound effect enabled because I can hear it when plugging in my simpit gear.

But none of that is happening while playing IL2.

 

It's just that the game, and only the game, will stop recognising peripheral inputs after you pause it for a few minutes or alt tab or do whatever to handle the interruptions that tend to come into every play session. 

Somehow IL2 just decides to stop listening to the devices, in a way that no other sim or game (that I have anyway) does.

 

@FTC_Princess is closer to the problem, as I do notice the issue happens less when I have all 1 million devices with USB power saving disabled. But since Microsoft intend to send windows updates constantly, and these updates tend to turn some of the USB power savings back on, it's not really a solution..

In any case power saving is a valid feature of the PC and we shouldn't have to permanently disable it just for one game.

Same problem happens to me (win 10, Quest 3, Open XR, necksaver, SimShakerWings, good quality power usb hubs. Never had this issue in other sims (like DCS).

It's not a 100% permanent solution but it works long enough at least in my case. I think I've had to redo this maybe twice in more than a year, and one of those times it was a new USB device.
I wouldn't expect a fix from the game itself TBH. The issue hasn't even been acknowledged AFAIK.

Thanks, yeah when I move some USB hubs around or lately I upgraded my CPU & RAM I found a lot of USB devices had gone and given themselves new entries in the device manager. I've got a monthly reminder where I go through and check any that have done this kind of thing and turn off USB power saving.

 

However the issue has come back recently after a new Pimax update. 

Previously Pimax allowed you to leave the headset on for a long time while paused etc, but now the new update they limit it to 5 minutes before turning off the displays. If I go get a drink, answer the phone, toilet, etc, that's long enough for IL2 to stop accepting input from all other devices due to this power management on the headset.

 

Again, like in the other instances, this is a thing that doesn't happen for any other sim/game and only in IL2. I can take the headset off as long as I want in "the other sim".

 

I don't expect a fix either, but I'm still asking for one.

Would be nice to know this kind of thing gets handled, before promoting Korea to our buddies and joining in on that.
