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.

HoloLens USB APIs

Can anybody here help point the way to how to solve this USB problem? I'm running this bit of code on a PC and also a HoloLens:

       string aqs = UsbDevice.GetDeviceSelector(0x03E7, 0x2150);
        var info = await DeviceInformation.FindAllAsync(aqs);
        foreach (DeviceInformation di in info)
            Debug.WriteLine("found " + di.Id + " => " + di.Name);

Pretty simple, right?

It detects the device correctly on the PC but not on the HoloLens. Why? I'm not that familiar with the USB APIs, but I thought the whole point of UWP was that the code would run on any Win10 platform? Am I missing a driver on the HoloLens, perhaps? Or does HoloLens just not support external USB devices?



  • Answering my own question here - I think it's to do with a missing driver. I'm not that familiar with Windows drivers though, so lots of reading on the horizon... if anyone has any insight into this it'd help me tremendously!
