I had the same problem with the same VCC1 of my Sony VGN-FE21H. Now I am
with 14.04 and it does not work either. Could I retake the process and
test what you need to try to fix it?

Thanks

Title:
  0ac8:c002 [Sony VAIO VGN-FE21M] Green/garbled/black webcam [0x0ac8
  0xc002] output

Status in linux package in Ubuntu:
  New

Bug description:
  I'm running Ubuntu 12.04.2 32bit and the webcam [0x0ac8 0xc002] of my
  Sony VGN-FE21M laptop gives green/garbled/black output when trying to
  use it in cheese, xawtv, vlc or skype. The suggested solutions in
  https://help.ubuntu.com/community/Webcam/Troubleshooting don't work.

  The output in the terminal when running 'xawtv' (see the attachment for a screenshot):
  v4l2: ioctl(fildes = 5 "/dev/video0", request = VIDIOC_QBUF, struct v4l2_buffer *data = { index = 0, type = V4L2_BUF_TYPE_VIDEO_CAPTURE, bytesused = 9682, flags = V4L2_BUF_FLAG_QUEUED, field = V4L2_FIELD_NONE, timestamp = { 18637,563 seconds }, timecode = { type = 0, flags = 0, frames = 0, seconds = 0, minutes = 0, hours = 0 }, sequence = 0, memory = V4L2_MEMORY_MMAP, m.offset = 2882400000, length = 16777216, input = 0 }) failed, Ongeldig argument (22, EINVAL) because the frame buffer is already in use

  The output in the terminal when running 'vlc v4l2:///dev/video0':
  [0xb53ed7a8] v4l2 demux error: Failed to unlock (VIDIOC_QBUF)
