Good, you have IME installed now, and it has been automatically updating.

Now I wonder if the INF file installer needs to be run again, or a newer version is needed. The INF file installer only installs what is "needed", but after the BIOS update new device(s) appeared, which are "unknown" most likely because their INF file has not been installed.

Try running the INF file installer from your board's download page again, it is INF driver ver:9.2.0.1015, for Windows 7 64 bit. There is no danger to running the INF installer again, if it finds nothing to do, it will do nothing.
