Hardware Compatibility: Detection of USB peripherals requires your Android device to physically support USB Host/OTG functionality. Some smartphone manufacturers require enabling "OTG Connection" manually in system settings. 2\. Power Requirements: High-power peripherals (such as external HDDs or unpowered USB hubs) may require an external powered USB hub to function correctly with your phone. 3\. Read-Only Diagnostic Tool: This application reads and displays standard Android hardware descriptors and metadata. It does not modify system files or access private storage content on connected USB drives. 4\. Trademarks: All product names, trademarks, and registered trademarks mentioned are the property of their respective owners.
