Pupil Core: No USB Camera detected for Microsoft Windows 10

[sunshineinsandiego]

Hi - I recently installed Pupil Core 3.4.0 and it is not able to detect a usb webcam from a DIY kit (Microsoft HD6000). The error messages I receive are here.

Additionally when I attempt to manually select a USB camera, I receive "camera already in use or blocked" in the GUI. As per the screenshot. Also see "Local USB Disconnected."

A screenshot of my device manager shows that the HD6000 is recognized in "Imaging Devices" but not in "Cameras".

I'm running Windows 10 on a new Asus laptop.

Any help would be appreciated. Thank you!

So I ended up getting this to work (albeit with some issues).
(1) Uninstalled my previously installed version of Python 3.9
(2) Installed Python 3.6.8 from Windows x86-64 executable installer: https://www.python.org/downloads/release/python-368/
(3) Followed steps 1-7 here: https://github.com/pupil-labs/pyuvc/blob/master/WINDOWS_USER.md
(4) Installed the MSVC 2010++ Redistributable from here: https://www.microsoft.com/en-us/download/details.aspx?id=26999 (Note the link to the redistributable on the github instructions is broken)
(5) Downloaded and installed the latest .whl file from the github instructions: https://github.com/pupil-labs/pyuvc/releases
using a virtual environment with Python 3.6.8 installed in step (2). (Note the typo in the instructions. pip install --upgrade uvc-0.13-cp36-cp36m-win_amd64.whl should read pip install --upgrade uvc-0.14-cp36-cp36m-win_amd64.whl.

This resulted in Pupil Capture working on Windows 10 with the HD6000 webcam. But with a few issues:

• Frame rate is consistently 6-8fps. Not sure if this is due to the driver not being able to handle a higher frame rate? See this link re: isochronous questions for that driver library: libuvc on Windows libuvc/libuvc#12
• Image quality is poor compared to using the same webcam used on a mac.
• Pupil detection much less consistent, possibly due to the two previous issued mentioned.

Thanks!
