"Hardware Not Found" Mbox mini 3rd gen

I just got this problem today. I searched the forums and found that this seems to be a common problem with this unit. More on Windows machines from what I have read. I have un/installed the drivers several times. Current ver is 1.1.3 just installed 1.1.4 with no results so I am back at square one.

System: Mac Pro OSX 10.7.5, 2.8 Ghz Quad Core Intel Xeon, 16 GB Ram, (4) 1 TB Drives, Mbox mini 3rd gen, Pro Tools Express.

Can someone please help me? Thanks
