+# USB Host Mode Validation
+
+## Overview
+
+This shell script executes on the DUT (Device-Under-Test) and verifies enumeration of connected USB devices.
+
+---
+
+## Setup
+
+- Connect USB peripheral(s) to USB port(s) on DUT.
+- Only applicable for USB ports that support Host Mode functionality. 
+- USB peripherals examples: Mass Storage devices (pendrives, SSD, hard drives, etc.), HID devices (Mouse, Keyboard, USB headset, USB camera, etc.)
