I'm surprised you got that far with an 8.2 IDF file. OpenStudio expects an IDF file of the same version of EnergyPlus it generates on export to IDF or when running simulations. For OpenStudio 1.5 this is EnergyPlus 8.1. If the IDF file doesn't have a version object it may try to open it, but may not work.
Keep in mind even if you have an 8.1 IDF HVAC elements won't import. While not at all supported you could edit the IDF to only contain internal loads, schedules, materials, constructions, surfaces, and zones and try to import that. If any of these object types have changed from one E+ version to the next this would not work.
