Latest firmware / driver for WD USB 3.0 PCIe card

Where can I obtain the latest firmware and driver for the WD USB 3,0 PCIe card?  The CD that came with the card has drivers from September 2010 – I have to believe its been updated since then.  I also want to flash to the latest firmware available, too.

My WD USB 3.0 PCIe card works, but I’m getting occasioanal disk errors reported in the event log saying that the disk controller (for the external drives) encountered an error.  I’d like to try updating to the latest available firmware and USB 3.0 driver to see if that resolves the disk controller errors.

The drivers you mentioned are the ones that show here

does not show any other driver than that
