Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

HP Mixed Reality Set HoloLens Sensors Driver Error

Hi,
I've purchased a HP Mixed Reality Set and when installing, the Mixed Reality Portal does not recognize the headset. It keeps saying that the headset needs to be connected. I see a code 31 error in Windows Device Manager which tells me that something prevents Windows from loading the driver, and I've tried to reinstall other drivers as well. But no luck.

The Windows Mixed Reality PC Check app says that all the prerequisites are being met.

Any idea?

Cheers, Sjoukje

  • Please make sure you connect your headset to a USB 3.0 port.

  • Hi SjoukejeZaal,
    Have you tried downloading and manually installing the driver? Here is the link to the 1803 HoloLens Sensor driver that you can try downloading and manually installing in Device manager: http://download.microsoft.com/download/4/D/9/4D9781EE-8896-4C49-B6C6-ABA79D85E50E/HololensSensors_10.0.17121.1001.zip
    Let me know if that works!

  • After purchasing the SAMSUNG Odyssey Mixed Reality everything worked but one day a week later found out the black screen in the helmet and the PC has been restarted. everything starts in the PC monitor and in the helmet black screen.What could be the cause? Reinstalled OS, and Mixed Reality to no avail. and originally worked at 60 Hz to 90 Hz transition was also black screen.
