C525 is already in use or blocked -- DIY eye tracker Core

[abucklaew753]

I'm having trouble getting the Pupil Labs Capture program to recognize my DIY eye tracker. I followed Pupils Lab Core DIY document (https://docs.pupil-labs.com/core/diy/) to build an eye tracker set up with the Logitech C525 (world camera) and Microsoft HD 6000 (eye camera). After downloading the Pupil Core software and plugging in the device, I received an error in the pupil_capture.exe: "

[Info] video_capture.uvc_backend: 1:5 matches C525 but is already in use or blocked.

[Info] video_capture.uvc_backend: Could not connect to device! No images will be supplied.

This is after manually adjusting camera drivers to libsubk and trying to run the Pupil Labs Capture program as an administrator.

Greatly appreciate any thoughts or solutions!

Troubleshooting already attempted:

I've tried updating the uvc as mentioned in other posts, but receive the error " ERROR: uvc-0.14-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform." (#2257)

I've downloaded the pyuvc code from github (except I could not find the package with the exact title 'libturbo-jpeg' but I found ' turbojpeg' instead).

I've manually used Zadig to change both the camera drivers to libusbk (both Interface 0 and Interface 2 for each device). (https://github.com/pupil-labs/pyuvc/blob/master/WINDOWS_USER.md#how-to-prepare-your-system-for-uvc-on-windows-8-and-later)
