There seems to be an issue with the drivers in the earlier versions of ProfileMaker specifically 5.0.5b allowing the i1iO to connect correctly.  Users are able to connect to the i1Diagnostics, Colorport and other software applications but PM5 will not find the scanning table.  The users can also see the i1 Pro but not the table.

The solution for this is to update to the latest version of PM5 or later than 5.0.8.  The drivers have been updated and once this update is installed the connectivity issue goes away.
