2.6.37: USB Thermaltake Dock: Only see's 1 HDD? [SOLVED, but which option fixed it?]

When I attach a dock with two HDD's on it in Linux, it only picks up one HDD,
this is with a Thermaltake BlackX Duet, is there a special module/etc
I need to load so it sees both drives on USB?

So I added some additional kernel options and now it seems fixed, but 
this is more of a shotgun approach, instead of rebuilding/rebooting 
several times does anyone know which module enabled support of > 1 HDD on 
the USB dock as shown below?

Even smart works when using usbmicron!
