We picked up a Blackmagic Intensity Shuttle (USB) and got the ETC to work with it right away in both the Blackmagic Media Express capture software and Adobe Premiere!
Our system is an iMac running the Blackmagic Desktop Video version 10.9 controller (driver) software.
Here are some screenshots with our settings:
•Blackmagic Desktop Video software:
•Blackmagic Media Express capture software (with purple/magenta ETC imagery):

How do these settings compare with yours?
