Hello,
According to this page : https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/installing-pix-hololens it should be possible to use PIX to do graphics debugging on the HL2
But I cannot get PIX to connect to the Hololens Device, I tried 127.0.0.1 like in the article, as well as the actual ipoverusb IP address of the device, nothing works, I always get this output :
Regular deployment and CPU debugging over USB works fine in VS.
The graphics debugger inside VS also fails to start with this message
I did a full reinstall using Advanced Recovery Companion to no avail
Thank you for your help

We’ve reproduced this issue and are currently investigating it. Thank you for your patience.
Hello, Welcome to Microsoft Q&A,
Based on my tests, PIX version 2310.30 and newer releases cannot connect to HoloLens and the version 2305.10 is fully functional. Try using 127.0.0.1 or UsbNcm IP to establish a connection. To find your UsbNcm IP, please refer to https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/using-the-windows-device-portal - connecting-over-usb.
