The storport driver is not the controller firmware. The storport driver is a Windows storage management driver. I suggest searching Microsoft's site to locate the storport driver for your operating system.
You should be able to expand the drive properties to get more detailed information. You can also review the hardware log for any errors related to the drives. The storport driver being out of date should not cause the drive LEDs to flash, but it may cause other issues that could lead to the LEDs flashing.
