DP83867IS: USB-2-MDIO Communication to Chip not working

Part Number: DP83867IS
Other Parts Discussed in Thread: USB-2-MDIO, , MSP-EXP430F5529LP

I am trying to verify a design with the DP83867IS in SGMII mode, but am having issues.  I cannot establish a link, and I am using the USB-2-MDIO to try to configure and manage the PHY for troubleshooting.  When I try to run the Find PHY command inside the software, I can see activity on the MDIO bus using an oscilloscope, although the data rate is only about 160 Hz (which seems to be VERY slow to me) and I cannot establish a connection to the PHY through the MDIO link.  Any help in getting this connected and working would be greatly appreciated.

HW Board: MSP-EXP430F5529LP

USB-2-MDIO Ver: 1.0

Firmware: USB_2_MDIO_F5.hex provided with the USB-2-MDIO installation
