Hi Pengqi,
It seems that our Streamstor devices are currently out on loan. We are requesting that the units be sent back, but it may be a few weeks before we can test an IMAQ card with a Streamstor device. This should work, but we cannot be 100% sure until we are able to test it ourselves. I will let you know as soon as I have a definite answer.
