This technical paper provides a comprehensive examination of the driver installation process, hardware architecture, and software integration of the UGREEN CM390 Bluetooth 5.0 USB Adapter. As Universal Serial Bus (USB) peripherals evolve to support higher wireless standards, the interaction between the host operating system (OS) and the device firmware becomes critical for achieving advertised throughput and latency. This document analyzes the CM390’s utilization of the Realtek RTL8761B chipset, explores the driver installation mechanisms across Windows and Linux environments, and evaluates the implications of Bluetooth 5.0 protocol support on system performance.
