Bbu3900 Usb Driver Direct

The BBU3900 backup battery unit, commonly deployed in outdoor telecommunications base stations, lacks native USB connectivity. However, diagnostic access to its State of Charge (SoC), voltage, temperature, and fault logs requires a serial-to-USB bridge driver. This paper presents the design of a custom USB driver for interfacing a host PC with the BBU3900’s maintenance port (typically RS-485 or CAN over a physical serial layer). We describe the driver architecture, command structure, and validation results using a CP2102 USB-to-UART bridge. The driver achieves reliable real-time data acquisition at 115200 baud with <5 ms latency.
