Public bug reported: My webcam Z-Star 305b was supposed to work out of the box [1], but it doesn't work in bionic. It only shows a black screen.
I've read lots of threads and tried some suggestions, but unsuccessfully. At present, I'm using bionic x86_64 with kernel 5.3.0-46-generic, before that I tried it with 4.15.0-96 and some previous versions. lsmod |grep gspca output is: gspca_zc3xx 57344 0 gspca_main 24576 2 gspca_zc3xx videobuf2_vmalloc 20480 1 gspca_main videobuf2_v4l2 24576 1 gspca_main videobuf2_common 49152 2 gspca_main,videobuf2_v4l2 videodev 208896 5 gspca_main,gspca_zc3xx,videobuf2_v4l2,videobuf2_common lsusb output is: Bus 002 Device 002: ID 8087:0024 Intel Corp.
