Dear all:
I try to fix the uvc driver on my mips platform.
But I got the messages as I append at the end of letter, the messages
are triggered by capture.c the sample c code at the official website.
I have some questions:
1. why the uvc resend the urb in uvc_video_complete?
2. from the log, it seems uvc keep catching when the VIDIOC_STREAMON
passed from v4l2 to uvc.
3. if the answer of 1 is yes; what will uvc does when he get
VIDIOC_QBUF and VIDIOC_DQBUF ?
    ( in my opinion, uvc should starting catpureing when he receives
VIDIOC_QBUF and stop when the buffer is full. Then it pass the buffer
above when he got VIDIOC_DQBUF. But from the log below, it start
captureing when he got VIDIOC_STREAMON. Am i right?)
4. if my assumption above is correct, uvc start capture at
VIDIOC_DQBUF and stop when buffer full. it should stop capture when
frame complete in the log appears.

appreciate your help,
miloody
