Hello,
starting from recent Kernels my ViMicro Webcam stopped working correctly im
mjpeg mode.
Looking at the driver sources I came across the UVC_QUIRK_FIX_BANDWIDTH
which has been activated for this camera:
Bus 002 Device 005: ID 0ac8:3420 Z-Star Microelectronics Corp.
Unfortunately this sems to do more harm than good. I made mjpeg mode work
fine again by removing the quirks altogether (see attached patch).
Regards
Sven
