Lenovo 300FHD web cam stopped working. It was working and after some version of OS update it stopped working. When i connected the same device to my mobile with OTG cable it is working so it is definitely a problem with drivers. I have reached to Lenovo and they mentioned it is something to do with common drivers of Mac OS which is causing this issue. Can someone help me here please.
You might want to try Lenovo again. My Logitech StreamCam is working fine with my M4 Pro MBP running Tahoe 26.1 and also on my M1 Pro MBP running the latest version of Sequoia (no Logitech software components installed), so there is not a generic issue with Tahoe or Sequoia and external webcams.
