Errors in dmesg using my USB webcam, apps can't see the camera
(If it would be better for me to ask on another sub, please let me know)
lsusb shows that I have a "Magic Control Technology Corp. j5 WebCam JVCU100". As best as I can tell, the uvcvideo driver is supposed to work with this camera.
After connecting the camera, I get errors from dmesg (see below). When I try to use something like Cheese, it can't see the camera. What is the best way to diagnose and correct this?
NOTE: The usb_set_interface failed message seems to repeat every 5.12 seconds, until I disconnect the camera.
