Good morning! First of all, I should point out that I have searched across the internet for others with this issue, but to no avail. I have a LarmTek camera USB Webcam 1080P - this is the link: www.amazon.co.uk/gp/product/B07VTPQ9NQ It worked under both Linux and Windows 10 (dual-booted - I need the latter for work from home) from the time I bought it until recently. It is permanently plugged into my desktop computer. I started the zoom client yesterday, and was greeted by a blank screen. The camera active light comes on, but no picture is available in the client. If I reboot the computer, then plug the camera in I get the following: ---------------------8<-------------------------- Nov 4 09:42:38 tristan kernel: usb 1-1: new high-speed USB device number 5 using xhci_hcd Nov 4 09:42:38 tristan kernel: usb 1-1: New USB device found, idVendor=0525, idProduct=a4a2, bcdDevice=30.00 Nov 4 09:42:38 tristan kernel: usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Nov 4 09:42:38 tristan kernel: usb 1-1: Product: HiEthernet Nov 4 09:42:38 tristan kernel: usb 1-1: Manufacturer: Huawei Nov 4 09:42:38 tristan kernel: usb 1-1: SerialNumber: 1234567891 Nov 4 09:42:42 tristan kernel: usb 1-1: USB disconnect, device number 5 Nov 4 09:42:43 tristan kernel: usb 1-1: new high-speed USB device number 6 using xhci_hcd Nov 4 09:42:44 tristan kernel: usb 1-1: New USB device found, idVendor=12d1, idProduct=4321, bcdDevice= 4.09 Nov 4 09:42:44 tristan kernel: usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Nov 4 09:42:44 tristan kernel: usb 1-1: Product: UVC Camera Nov 4 09:42:44 tristan kernel: usb 1-1: Manufacturer: Ruision Nov 4 09:42:44 tristan kernel: usb 1-1: SerialNumber: 20200416 Nov 4 09:42:44 tristan kernel: usb 1-1: Found UVC 1.10 device UVC Camera (12d1:4321) Nov 4 09:42:44 tristan kernel: usb 1-1: Failed to query (GET_INFO) UVC control 12 on unit 2: -32 (exp. 1).

All of these kernels have the same result. - I don't see any other error messages in my logs - The camera continues to work under Windows 10, so I don't believe it is a hardware issue. Please can you advise me how I can debug this issue? Unfortunately I am not a heavy user of the camera, so I can't pinpoint exactly when the problem started. Many thanks for your continued development of the code to manage these devices, and for supporting me with this issue. -- Paul |
