This Intel USB 3.0 port supports the KeyBot II feature. Furthermore, the manual states you must connect your USB keyboard to this port if you wish to take advantage of it. Reference p. 2-14 of the User's Guide for its location. Unfortunately, the port will not recognize any device once in the Windows environment. ASUS Tech Support verified my keyboard and mouse work fine via this port while in the UEFI environment. Hence, they concluded the port is fine, and therefore it must be a Windows issue. LEDs within my thumb drives illuminate, but there is no Windows sound when inserting or removing the drives. The latest and greatest Win 10 Pro 64-bit version is installed. All other 10 USB ports recognize devices in Windows, make sounds, etc.. My keyboard and mouse are working normally in other ports. If anyone else has experienced this behavior on a M8E/A motherboard, please chime in? I would also like to hear from folks using this port without issue. Thanks.
