Coming from https://sourceforge.net/p/linux-uvc/mailman/message/37622481/ without getting any response... I have a combined USB Camera with microphone: Bus 003 Device 004: ID 0408:2090 Quanta Computer, Inc. Astro HD Camera Some while ago I had the camera working, just needed to disable the microphone because if issues with pulseaudio. Now with 5.15.23-gentoo, nothing works anymore with that camera, no video and no audio input: https://forums.gentoo.org/viewtopic-p-8693533.html Is this the right place to discuss this hardware? I'm testing with guvcview, and it does not start anymore: Mar 02 10:41:49 [kernel] usb 3-12.2: USB disconnect, device number 12 Mar 02 10:41:57 [kernel] usb 3-12.2: new high-speed USB device number 14 using xhci_hcd Mar 02 10:41:57 [kernel] usb 3-12.2: New USB device found, idVendor=0408, idProduct=2090, bcdDevice=21.17 Mar 02 10:41:57 [kernel] usb 3-12.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Mar 02 10:41:57 [kernel] usb 3-12.2: Product: Astro HD Camera Mar 02 10:41:57 [kernel] usb 3-12.2: Manufacturer: QCM Mar 02 10:41:57 [kernel] usb 3-12.2: Found UVC 1.00 device Astro HD Camera (0408:2090) Mar 02 10:41:57 [kernel] usb 3-12.2: No streaming interface found for terminal 9.
