I put this unit in the same machine as a Rocket Port multi-port card. Windows 7 only recognized 4 of the 8 ports but that was sufficient for the day and I didn't investigate further.I have used other StarTech serial cards with great success where cheaper cards in the same application have failed.Worked fine.

It did NOT come with a low profile adapter. It does work on Server 2016 with the included drivers.Working goodWe are using 2 of these in productions system right now.
