Blackmagic Intensity Shuttle update

Ed Friesma, Application Editor for Key Code Media, mentioned the following:  After working with a walkin client yesterday trying to install the Blackmagic Intensity Shuttle for HDMI capture,  I found a big gotcha that’s not clearly mentioned in any of the promotional materials.  If you’re connecting via USB 3.0 it needs to have the NEC USB3 controller chipset.  Currently no other one will work properly.  I don’t know if Blackmagic plans to qualify other USB 3 chipsets later or if they’ve given up and are focusing on Thunderbolt.
