The Xiaomi 14T Pro can not recognize third-party drives and earphones due to the way it manages device compatibility. To enhance interoperability with external devices, Xiaomi has implemented an OTG (On-The-Go) device recognition switch within the settings. When you want to connect a third-party device, you need to ensure that this OTG feature is enabled. Once activated, it allows for direct connections to other devices via USB. However, keep in mind that this feature will automatically turn off after 10 minutes of inactivity for safety and energy conservation. By enabling OTG and properly connecting your devices, you can significantly improve compatibility and functionality.
