Webcam not working in browser

Using LMDE4 on Aspire 5630-6091, with with 046d:0896 Logitech Orbicam (gspca_vc032x driver), the webcam works fine in softwares like cheese or guvcview. But it does not work when trying to use Firefox or Google Chrome in sites like Google Meet or webcamtests.com . Chrome does not even find the camera. Firefox, find the camera (webcamtests.com), lists it, but does not play (the message is shown: "AbortError: Starting video failed"). I allowed Firefox to use the camera when asked.
