Hello, 
I am totally newbie to this ML.

Now I am trying to build livecam on ARM platform.
xawtv works well with camera (0c45:62c0=Sonix USB 2.0 Camera) but,
webcam(this is livecam program in xawtv. not camera device. pretty
confusing..) did not work.

Precisely, webcam could capture first image (very noisy), but
failed in the second capture. It failed at ioctl(VIDIOC_REQBUFS).

UVC driver stack is

uvc_free_buffers()
 queue->buffer[i].vma_use_count = 1 (shoud be 0)
uvc_alloc_buffers()
uvc_v4l2_do_ioctl()

I have no idea abount this issue.
Does anyone have solutions ?

Regards.
