We purchased this adapter on Amazon (
http://www.amazon.com/StarTech-com-E.../dp/B003GSGQF6) because we did not know this was yet another displaylink powered adapter. It specifically said it had 10.8 support... Unfortunately, the EXACT same issues happen with the displaylink drivers.
FIX THIS PROBLEM!!! You are only damaging your companies name.
