When you update to driver version 10.1 you also need to update your Open IO Plug In for Avid. If you did not perform this step, the hardware would not be recognized. If you would like to use driver version 10.1, simply use the AJA Uninstaller in the Applications>AJA Utilities folder. Then install version 10.1 as well as the associated version of the Open IO Plug In.
Driver and open IO Plug Ins are found here:
