Looks like insufficient USB bandwidth available to support the 24
MB/second required for uncompressed analog video.

Is this on an x86 PC?  Or some embedded target such as ARM?  If the
latter, then the answer is almost certainly that the USB host
controller implementation is garbage and cannot handle the throughput.
