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.

Can't find Hololens from Windows 10 PC connected to it via USB

Running this on a Japanese Windows 10 OS. Hololens just arrived at work a week ago.

Looking just to view the hololens display on a Windows 10 PC.

Installed this VSToolsForWindows1C (latest VS2015 w/ Updates 3 as of 1/26/2017).
Ensured that Tools (1.4) and Windows 10 SDK (10.0.10586) were installed. Just now double-checked that they are.

Did not install Hololens Emulator. Is it required to view the display?

    So initially, the hololens was connected outside of the company network. Attempting to connect to it using a computer on the company network (running through a proxy) failed. Maybe that makes sense for connecting over wifi, but not really for connecting over USB.

    Setting up the Hololens to use the company network, the device portal setup went smooth as butter and I was able to use Live Preview with ease.

    In short, connecting via USB wasn't solved. Connecting via Wifi (while on the same network and proxy) the problem got solved perfectly.

    I sincerely appreciate your help, DavidKlineMS!
    Thanks a lot!

    You will need to connect to the HoloLens using the Windows Device Portal. Once connected, navigate to the Mixed Reality Capture page and click the Live preview button.

    Thanks!

    Hello David,
    Thanks a ton for the response. I saw a previous thread you posted with similar instructions, regarding employing the Device Portal in order to get the Hololens detected by PC.

    I'm using W10 Enterprise (Japanese as primary language). The network runs through a proxy with UDP/IP.

    Following the instructions in order on that link, having previously enabled Developer Mode on the Hololens, I turned the Device Portal switch to On.
    Made sure the proper VS install requirements were filled.

    The device is connected to wifi already, but I got stuck on the Connecting over Wifi/USB part.

    After connecting the device to a USB 3.0 port on the Windows 10 PC, I enter http://127.0.0.1:10080 into the address bar using the Edge browser.

    This is the error it displays:

    Basically says
    "Can't display this page

    • Verify the address entered is correct
    • "

    I've tried to restart both the hololens and the PC after enabling device portal, but the same error persists.

    Btw, Number of paired devices is 0.

    Update:
    Just for good measure, in the Connect over USB instructions the first step Install the Tools I initially installed VS2015 with Updates 3, Unity 5.5.0f3,Vuforia only. I now installed the Hololens Emulator that's linked here http://go.microsoft.com/fwlink/?LinkID=823018. Let it complete and restarted. Entering in http://127.0.0.1:10080 in Edge after reboot gives the same "Can't display page error".

    Furthermore, I noticed that upon connecting the Hololens to the PC, there is no notification whatsoever on either Hololens or PC that indicates a USB device (or any device) has been connected.

    I located the IPv4 address of the hololens via Settings > Network & Internet > Wi-Fi > Advanced Options. And then tried to enter it into Edge using https://. It gave me the same error as connecting over USB ("can't display page").

    I am now attempting to install:

    • Windows 10 mobile emulator (10.0.14393)
    • Windows 10 SDK (10.0.10586)
    • Windows 10 SDK (10.0.10240)

    in addition to the "Tools (1.4.1) and Windows 10SDK (10.0.14393)" that was installed before I made the initial post of this thread.

    If it still doesn't work, I will try to uninstall and reinstalling VS2015 community.

    Update:
    I installed the above SDKs and the hololens is showing up under USB Devices in Device Manager.

    Windows Phone IP over USB Transport (IpOverUsbSvc)) is _not _running in Computer Management > Services.

    Google Chrome, Firefox and Edge all give the "Can't display page" error when entering http://127.0.0.1:10080. I've tried connecting the HL to every USB port (motherboard and Case) on the PC.

    Any more help would be extremely appreciated.

    Up until now I've only enabled Device portal on the HL, not on the PC. Maybe that's the reason I can't connect?

    I've triple checked both PC and HL have the latest updates.

    Trying to enable dev mode on the W10 PC produces the error, "Developer Mode Package failed to install. Error Code 0x8004005."

    Following these steps here:
    https://social.msdn.microsoft.com/Forums/en-US/a7e94e5b-db19-492f-a1c1-d5fa3aa87d0d/enabling-developer-mode-fails-with-error-code-0x80004005?forum=Win10SDKToolsIssues

    Get stuck at "5. Select the package for Windows Developer Mode."
    Clicking on Add feature, says "There are no features to install"

    Failed to install error persists even with HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU\UseWUServer set to 0.

  • I believe part of your issue lies in the fact that the IPOverUSB service is not runnin on your machine. Can you please try starting it and see if you can connect to the HoloLens using http://127.0.0.1:10080?

    On successful connection, you should see a page asking you to pair the device.

    Thanks!

    @DavidKlineMS

    Thanks for the replies. I will not attempt to enable device portal and developer mode on the PC. I'll keep both enabled on the HL only.

    Hmm, still failing to connect.
    Here's a screenshot showing the hololens connected in Device Manager, the IPoverUSB service running in Task Manager, and VS2015 Updates (3) installed.

    Note that I reinstalled VS2015, and verified the mandatory **Tools (1.4) and Windows 10 SDK (10.0.10586) ** was checked.

    I've triple-checked that the HL's Developer mode and Device Portal switches are on.

    Update:
    Might be unrelated, but I've just now found out that plugging in a Kinect v2 to this PC (with SDK v2.0 installed), and running Kinect Configuration Verifier tool, there appears to be a problem with the USB controller.

  • FYI, another resolution to this issue may be the USB port you are using.
    I initially was using a USB 3 port (which I've used to flash my HoloLens many times) and had the same issues.
    On a whim, I switched to an older USB2 port and it's working perfectly now. SO try different USB ports if you are having this issue.
