USB 3 / eSATA support

I am working on setting up a Bacula backup to an external hard drive.  
The server I am running this on has an on-board USB 2 controller, 
however the external USB 3 SATA drive doc I am using is only being 
recognized as USB 1.  It does correctly load as USB 2 or USB 3 if I move 
it to my windows machine which has both USB 2 and USB 3 ports.

Before I spend money adding a USB 3 card to the server in order to get 
the external drive doc to load as USB 3, I was wondering if anyone had 
any good or bad things to say about FreeBSD's USB 3 support.

Would I be a lot safer spending money on an eSATA card and a eSATA doc, 
knowing that this would give be better performance, but would prefer to 
not spend any more money than I have to.

Or maybe someone would have an idea as to something I could tweek to 
get more than 1MB/s transfer speed from my existing setup, if I could 
get the full speed of USB2.0 this would run adequate for my needs.

Current machine is running a Biostar TPower N750 Motherboard, and the 
external drive doc is an INEO I-NA317U-Plus.
