Headset not detected (108)

[SlowerPigeon]

I keep getting the 108 error trying to start the WMR for SteamVR app. Tried running SteamVr directly, tried running this app, tried running the app from Window Holographic Desktop App.

I feel like I am missing something obvious. (OS Build 16299.64)

Any suggestions?

same here.
Intel 4930 k cpu, 32 gig ram, NVidia titan pascal
Windows 10 updated, NVidia most current drivers
Samsung odyssey properly installed and functioning well in mixed reality portal

trouble started after installing 'windows mixed reality for steam vr'
no steam vr games launch - always get steam vr error that headset not detected
then mixed reality portal gives the error 2181038087-7
quitting mixed reality portal and restarting it does not resolve issue
unplugging/replugging the hmd does not resolve it

only reboot works

Thanks for letting us know. Do you see this problem only when using SteamVR? Or does it also occur when trying to use the Windows Mixed Reality Cliff House?

Please make sure to send us feedback on this from the Windows Feedback Hub. To help us get the most from your feedback:

1. Put "SteamVR" in the title (assuming this only occurs when you're using SteamVR. That helps our team to find it.

2. Attach a SteamVR System Report to the feedback. You can create one by clicking the menu in the SteamVR window and clicking "Create System Report". Save the report and attach it as a file in Feedback Hub.

I had your issue OP but I ended up uninstalling and reinstalling SteamVR altogether and now it picks it up, give that a shot.

Hi Jonathan, others,

I am going to follow the steps + maybe reinstall SteamVR; however, in my case, I notice that the headset is funky with the Cliff House (pre house actually) as well.

The device makes a connection noise, but I have to plug and unplug either the USB or HDMI to finally get it to recogonize. Once it's setup it seems to work, but it requires a lot of playing.

Hardware: Dell Alienware 17 r1, i7-4900mq, 32GB ram, GTX780m.

Reinstalling SteamVR worked for me as well.

Thank you guys! I'm having the same issue. I'll reinstall SteamVR

Did anyone find a solution? I tried reinstalling SteamVR and got the same problem (as well as restarting my computer, ensuring that GPU drivers were up to date, etc.). My WMR works fine in Cliff House, but SteamVR can't seem to detect the headset.

Any help here would be great.

Ever since this thread I posted before reinstalling SteamVR fixed my issue. Well I've had OTHER issues happen out of nowhere where I've had to basically reinstall Windows MR to fix those problems! Weird right? I guess it's still relatively new?

I'd recommend unplugging the headset from both USB and HDMI, and removing the controllers from your computer (they are stored as bluetooth devices). Then you have to launch the portal, go in to settings, and the last option is "uninstall". After uninstalling close the portal, plug everything back in, and launch the portal again to go through the setup.

If it still doesn't work after that I don't know what else to tell you :(

I initially had the same problem on one of my machines. (I don't recall having the same issue on my Surface Book 2 -- as I recall, SteamVR bridge just worked without special steps with my WMR headsets.)

But on my desktop machine, SteamVR have me the 108 error. To resolve it, I manually installed
"Windows Mixed Reality for SteamVR" from the Steam store, then manually launched that.

I don't get why SteamVR is only trying to detect a VIVE... I have the Dell Visor and after several days trying I can't even get SteamVR (with Windows Mixed Reality) to work properly.

Guys i know its soo stupid and i did the samething but when i down load "windows mixed reality for steamvr" on steam that worked

I've tried all the advises listed above - none of them worked for me. I am using Acer H100 WMR headset.
When starting SteamVR app I am notified with Headset Error 108, and sometimes, soon after, with another error, which says "Unexpected SteamVR error" which shuts SteamVR down.

Everything works perfectly when launching Windows Mixed Reality directly from Windows.

PC is pumped enough to remove all the errors connected to PC hardware performance issues, and nothing that I've tried so far helped.

check "C:\Users\username\AppData\Local\openvr\openvrpaths.vrpath"
check if "external_drivers" is null
if it is null, assign your MixedRealityVRDriver folder path to it.
like this: "external_drivers" : [ "C:\\Program Files (x86)\\Steam\\steamapps\\common\\MixedRealityVRDriver" ],

Sorry for the Necro, but had to thank you for this information. That was my issue and this helped. Thanks!
