webcam does not report higher resolutions on windows-10

Question

BRIO 4K Stream webcam does not report higher resolutions on windows-10-pro machine while on windows-10-home machine everything works ok.

Any idea how to troubleshoot this issue ?

What i have tried so far:

Take webcam driver from working machine and install on problematic machine
Update windows to latest version
Use windows-media-foundation API to list modes instead of directshow
Google for logitech brio specific issues and anything related that came into my mind
Opened issue on logitech support site
Connected usb3 hub before webcam
Tried every USB port on motherboard
Connected camera to usb3.0 port on Geforce RTC 2070 via USB-c to USB-c cable

Problematic machine info and FFMPEG command:

Correct output on different machine:

Please note additinal s=1920x1080 fps=60 and s=4096x2160 fps=30 modes not present in problematic output.

Thanks, Alex

BRIO 4K Stream webcam requires USB 3.1 port to report UHD resolutions.

I tested PEX-U31-01 Gembird 2-port USB 3.1 PCI-Express add-on card

Don't forget to connect SATA power cable

When connected to PEX-U31-01 card camera reports UHD modes:

[dshow @ 000001a82352a840]   vcodec=mjpeg  min s=2560x1440 fps=5 max s=2560x1440 fps=30

[dshow @ 000001a82352a840]   vcodec=mjpeg  min s=3840x2160 fps=5 max s=3840x2160 fps=30
[dshow @ 000001a82352a840]   vcodec=mjpeg  min s=4096x2160 fps=5 max s=4096x2160 fps=30
[dshow @ 000001a82352a840]   vcodec=mjpeg  min s=4096x2160 fps=5 max s=4096x2160 fps=30

Problem is that capture does not work for 1080p and higher resolutions with PEX-U31-01 card. Logitech Capture application shows Camera not connected message. FFMPEG does not receive the frame.

webcam does not report higher resolutions on windows-10
