Cheese cannot seem to find it, and I did not see it listed on your list of supported devices, so I thought I would bring it to your attention. Here is what I see from running lsusb: Bus 001 Device 006: ID 0711:3108 Magic Control Technology Corp. j5 WebCam JVCU100 Also, running lsusb -d 0711:3108 -v | grep "14 Video" returns Couldn't open device, some information will be missing bFunctionClass 14 Video bInterfaceClass 14 Video bInterfaceClass 14 Video bInterfaceClass 14 Video bInterfaceClass 14 Video So, looks like the Linux UVC driver at least recognizes the webcam.

If you can test it on both (just plugging it in and checking if it works), it's even better. When it comes to capturing USB traces, I haven't tried that for probably at least 15 years, so I'm afraid I can't help. > On 1/30/22 6:00 PM, Laurent Pinchart wrote: > > On Sun, Jan 30, 2022 at 12:12:53PM -0600, Mohammad wrote: > >> Is there a way around this problem?
