If not already solved, I recommend this:
Get PSID of adapter (seen with ibv_devinfo). Check its capabilities to confirm it is IB and FDR as you suspect.
Confirm in the WinOF release notes, that the operating system is compatible with the WinOF driver version.
Also confirm in the WinOF release notes that the firmware rev is compatible with the WinOF revision.
If needed re-install the WinOF driver.
If all else fails, try re-seating the adapter.
HP FDR IB Adapters 545M(702213-B21) is not supported on Windows, only Linux. You have to use HP 544+ adapters
