Hi,

I have a new UVC device, not listed on http://www.ideasonboard.org/uvc/:

Bus 001 Device 003: ID 04f2:b3b2 Chicony Electronics Co., Ltd

This is a webcam builtin a toshiba satellite laptop. I can't get it to
work. Here are the error messages:

$ xawtv -c /dev/video0
This is xawtv-3.102, running on Linux/x86_64 (3.12-1-amd64)
xinerama 0: 1920x1080+0+0

EINVAL) because ioctl request or ioctl data is not valid
libv4l2: error dequeuing buf: Invalid argument
v4l2: ioctl(fildes = 4 "/dev/video0", request = VIDIOC_DQBUF, struct
v4l2_buffer *data = { index = 0, type = V4L2_BUF_TYPE_VIDEO_CAPTURE,

because ioctl request or ioctl data is not valid
libv4l2: error turning on stream: Invalid argument
libv4l2: error reading: Invalid argument

Is there any extra information I can send you to help make this driver
supported?

Thanks!
Marco
