Usb Driver — Bbu3900
A: No. Each Huawei device has its own USB vendor/product ID. The BBU3900 driver is specific to baseband units with UMPT/WMPT boards.
Before diving into the driver, let’s establish a foundational understanding of the hardware.
The BBU3900 is a baseband processing unit from Huawei’s Series 3900 multi-mode base station. It is responsible for:
The BBU3900 features several interface panels: E1/T1 ports, FE/GE optical ports, alarms ports, and—crucially—a USB port. This USB port is used for:
However, connecting a PC’s USB cable to the BBU3900’s USB port does not yield a standard COM port immediately. Instead, a proprietary USB-to-Serial converter chip inside the BBU3900 requires a specific Windows driver.
The BBU3900 USB driver is a small but mission-critical software component for anyone who needs direct, physical access to Huawei’s baseband infrastructure. While installation can be plagued by driver signing issues, PID mismatches, and Windows version quirks, the detailed steps provided in this guide will help you achieve a stable connection.
Always start by identifying your BBU3900’s exact hardware revision and your Windows build. Use the latest drivers from official Huawei channels when possible, and don’t hesitate to temporarily disable driver signature enforcement during installation.
With the driver correctly installed and a terminal tool like PuTTY or LMT, you unlock the full command-line power of the BBU3900 – from real-time monitoring to advanced troubleshooting.

Huawei BBU3900 , "USB drivers" typically refer to the Huawei HS-USB Ethernet Adapter
drivers required to establish a local maintenance terminal (LMT) connection between your laptop and the BBU's USB port (often located on the 1. Driver Identification & Compatibility
The standard driver used for local commissioning and management is the HUAWEI Wireless HS-USB Ethernet Adapter : 1.03.00.00 or later is commonly used. Operating Systems : Compatible with Windows 10, 8.1, 7, Vista, and XP (both 32 and 64-bit).
: It allows your PC to treat the BBU's USB connection as a virtual Ethernet interface for local management. 2. Installation Procedure
To install the drivers manually if they are not automatically recognized: Extract the Package
: Download and extract the driver compressed file (often named Huawei_Mobile_Driver or similar). : Open the folder and execute the installer (e.g., Huawei_Mobile_Driver_v1.0.exe Wizard Steps
: Follow the on-screen prompts, accept the license agreement, and finish the setup. Connect Hardware
: Insert the USB cable into the BBU's maintenance port. The PC should now detect a "Huawei HS-USB Ethernet Adapter" in the Device Manager 3. Usage in Commissioning bbu3900 usb driver
The USB port on the BBU3900 serves two primary maintenance roles: USB Flash Drive Commissioning
: You can use a standard USB stick to load software and configuration files without a PC. The BBU's will blink rapidly during this process. Local Maintenance Terminal (LMT)
: When using the USB-to-PC cable, the driver enables you to log in to the Default Web LMT Password Common Command DLD CFGFILE
via the MML command line to download configuration files after logging in. 4. Technical Documentation
For specific board layouts and cabling, refer to the following official guides: BBU3900 User Guide : Comprehensive hardware and port descriptions. BBU3900 Slot Assignment Guide
: Details where the UMPT or GTMU boards (which house the USB ports) should be placed in the chassis. driver download link
Huawei BBU3900 does not typically require a standalone USB driver for its physical ports, as the onboard USB slot is primarily designed for automatic base station upgrades and data configuration using an encrypted USB flash drive.
If you are attempting to connect a PC to the BBU3900 for maintenance, the connection is usually established via a Fast Ethernet cable
to the maintenance port, and management is handled through the Huawei Local Maintenance Terminal (LMT) or Web LMT. Access & Software Management A: No
For field engineers and technicians, the following tools and methods are standard: Local Maintenance Terminal (LMT)
: A desktop tool used for commissioning, troubleshooting, and configuring Huawei network elements like the BBU3900. It is often installed via a specific setup script ( ) within the installation directory. USB Flash Drive Commissioning
: You can perform an automatic upgrade by inserting a USB flash drive containing the required software and configuration files directly into the BBU's USB port (e.g., on the UMPT board). Ethernet Connection
: Direct login is typically done by setting a static IP on your laptop that is compatible with the BBU's default maintenance IP. Driver Resources
