[0ac8:c002] Z-Star Camera VGP-VCC1 (Vaio VGN-FE21H)

[noric]

This issue has been already reported and studied in bug #1134565, which is now closed due to the breaking down of the reporter's laptop: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1134565

I'm running Ubuntu 14.04.3 32bit and the webcam [0x0ac8 0xc002] of my Sony VGN-FE21H laptop gives green/garbled/black output when trying to use it in cheese, xawtv, vlc, “qv4l2 --raw -d /dev/video0”.
This is with kernel 3.19.0-32.

Cheese outputs this:
** (cheese:3998): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

And here's the output of “dmesg” while I run cheese or vlc:
[ 951.384415] gspca_main: ISOC data error: [6] len=0, status=-71

Here's the output of “v4l-info” :
### v4l2 device info [/dev/video0] ###
general info
    VIDIOC_QUERYCAP
        driver : "vc032x"
        card : "USB2.0 Web Camera"
        bus_info : "usb-0000:00:1d.7-8"
        version : 3.19.8
        capabilities : 0x85200001 [VIDEO_CAPTURE,?,READWRITE,STREAMING,(null)]

I’ve also tried kernel version 4.4.0-21 (with Ubuntu 16.04 live cd) and there I have not even the /dev/video0 device. The camera is recognized by “lsusb”, but /dev/video0 doesn’t exist.

Please let me know if I can help solve this issue.

Thanks

Some parameters around the bug may have changed, but the main issue is the same, same webcam, same garbled green output with some strips of correct video, e.g. the very top. I actually do have a /dev/video0 though. Initially I just get a black screen as output that seems non-functional (e.g. cheese fails to get a black screen photo, but I manage to get the green if I preload compat and cheese will take captures of the garbled output:

LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so cheese

I am attaching a screenshot. The green can vary quite a bit, sometimes more pink, etc... Not entirely random, but clearly garbled.

This is now in 18.04 with the Mate desktop environment.
