The genuine iusb3mon.exe file is a software component of Intel® USB version 3.0 eXtensible Host Controller by Intel Corporation.
The Intel® USB 3.0 Monitor (iusb3mon.exe) in the USB 3.0 eXtensible Host Controller Driver is a background Windows service that monitors Plug and Play status of all USB ports and generates pop-up event notifications. It is optional and can be uninstalled by selecting "Intel® USB 3.0 eXtensible" (or "…Host Controller") in the Control Panel "Uninstall a Program" applet. (All Windows OS have a core USB Monitoring system.) USB 3.0 ports and plugs (colored blue) have more pins than 2.0 versions because 3.0 adds dual-bus architecture so that USB 2.0 (at Full, Low, or High speed) or 3.0 (SuperSpeed) can take place simultaneously. Higher wattage power transmission is also allowed. Plugs and ports for 2.0 and 3.0 are still forward and backward compatible but if a device designed for 3.0 is plugged into 2.0, the Monitor will remind the user.
