Troubleshooting noname USB webcams isn't going to be possible - unless there's a generic issue with the transport protocol in question.
I have four Raspberry Pi 4 each with a Logitech BRIO 4K USB3 webcam attached.
They used to record 4K mjpeg streams using ffmpeg (to a file server) in full 3840x2160 resolution at 30 fps.
Using VL805 FW version: 000137ab the webcams were only able to do 1920x1080 resolution.
After downgrade using:
sudo vl805 -w /lib/firmware/raspberrypi/bootloader/beta/vl805-00013701.bin
4K worked again
