Well, you can get a thunderbolt to firewire adaptor or a proper hub but it sounds like you're trying to connect two computers to one drive. Is that right?

If so, you would need to have the drive configured as a server, which may or may not be possible. The easiest thing to do would be to enable file sharing on the first mac pro, and then have the second mac pro connect to the first over the network. It can then access the drive. If the file sizes are large, you will of course need a network with decent speeds.

because it says so on the website and on the product reviews on amazon. *The Thunderbolt™ Station 2 can only support dual monitor configurations if your computer’s hardware can support dual monitors via Thunderbolt™ and if:

• One of the displays is a Thunderbolt™ Display
  or
  
• The second display is connected to a second Thunderbolt™ Station 2 or another Thunderbolt™ 2 device*
  
  Do you use this dock?
