I have a Sony SRG-120DU camera. When I connect via USB3, I get dmesg:

Though discontinued some years ago, Sony advertised this camera as
supported by UVC, as "plug and play" without an additional driver. It
does produce a video signal on Windows via USB3, but fails on Linux. I
am running Linux Mint:

Thank you for your time,
