I have a few Seagate Freeagent Go external HDs and a Seagate UBS Dock Hub that i am trying to connect to the AppleTV. I am unable to make it see all the drives plugged into the hub. Has anyone else had difficulties trying to get a hub to work? Has anyone had a hub work on the AppleTV? Any suggestions are greatly appreciated.

im assuming you already have USB working you are just having issue with a hub? From my experience the only hubs that have ever worked have been ones that are powered hubs, ones that try to get the power from the device they are plugged into wont work with the AppleTV.
