VIDIOC_S_FMT can return EBUSY either when the device is already streaming or when another process has acquired a "streaming privilege". Basically, this means another process has already called one of the following ioctls: VIDIOC_S_INPUT VIDIOC_S_PARM VIDIOC_S_FMT VIDIOC_TRY_FMT VIDIOC_REQBUFS Please apply the attached patch and check the kernel log. The driver should report every process that acquire or release streaming privileges, as well as attemps to call VIDIOC_S_FMT while streaming.

This is quite weird. The camera starts streaming without any problem, but after streaming for a while it fails to answer all USB requests. The requests sent before stream start probably confuse the camera somehow. I'll have another wild guess, could you please try the attached patch ?
