The Huawei BBU3900 (Baseband Unit) typically requires a specific driver to enable a local maintenance connection via its USB port. This is usually the HUAWEI Wireless HS-USB Ethernet Adapter driver. Key Driver Information
The driver creates a virtual Ethernet connection over USB, allowing you to access the BBU's WebLMT (Local Maintenance Terminal) or other management tools. Driver Name: HUAWEI Wireless HS-USB Ethernet Adapter Version: 1.03.00.00 (commonly found).
Supported Systems: Windows 10, 8.1, 7, and XP (both 32-bit and 64-bit).
Official Source: For authorized engineers, the most secure source is the Huawei Support Enterprise Portal. How to Install and Connect
Download and Extract: Ensure you have the driver package (often part of the "Local Maintenance Terminal" software suite).
Run as Administrator: Right-click the installer (e.g., ADB-USB-driver.exe or the HS-USB setup) and select Run as Administrator.
Physical Connection: Connect a USB cable from your laptop to the USB port main processing board. Verify in Device Manager: Open Device Manager on your PC. Look for " HUAWEI Wireless HS-USB Ethernet Adapter " under Network Adapters.
If it shows a yellow exclamation mark, right-click it and select Update Driver, then browse to your local driver folder.
Configure IP Address: Once installed, the USB connection acts as a LAN port. You may need to set a static IP on your PC (often in the 192.168.0.x range, depending on your BBU configuration) to access the LMT. Common Troubleshooting
Connection Not Recognized: Ensure you are using the correct USB port on the BBU (often labeled "USB" or "LMT"). bbu3900 usb driver
Driver Errors: On newer Windows versions, you may need to disable Driver Signature Enforcement to install older legacy drivers.
Power & Status: Check that the BBU is fully powered and the RUN indicator is flashing normally before attempting a connection.
The Huawei BBU3900 USB driver is a critical software component used primarily during the local maintenance and commissioning of the BBU3900 (Baseband Unit) in Huawei's BTS3900 series base stations. It enables a PC to communicate with the BBU via its USB port, typically through a specialized USB to Ethernet LMA (Local Maintenance Adapter) cable. Core Functionality & Purpose
The USB interface on the BBU3900 serves several vital roles in site deployment and maintenance:
Local Maintenance Terminal (LMT) Connection: The driver allows engineers to connect their laptops to the BBU to access the LMT or WebLMT software for configuration and troubleshooting.
Base Station Commissioning: During initial setup, the USB port is used to download software versions, license files, and configuration data directly to the unit, often referred to as "USB commissioning".
Security: To prevent unauthorized access, the BBU3900 USB port includes encryption features to ensure secure data transfer between the unit and the maintenance PC. Hardware Compatibility
The driver is designed to work in tandem with specific Huawei hardware:
Main Control Boards: It supports communication with boards like the GTMU (GSM Transmission & Management Unit) or WMPT/UMPT (Universal Main Processing & Transmission) boards, which house the physical USB port. The Huawei BBU3900 (Baseband Unit) typically requires a
LMA Cable: Standard USB cables are often insufficient; engineers typically use a BBU3900 USB 3.0 to Ethernet Cat5 Network LMA Cable (Part Number: 04050386) to bridge the connection. Key Specifications Bbu3900 USB 3.0 to Ethernet Cat5 Network Lma Cable
BBU3900 USB Driver is a specific software component used to facilitate communication between a technician's computer and the Huawei BBU3900 (Baseband Unit)
during site commissioning, maintenance, or software upgrades. Core Functionality
When a laptop is connected to the USB port of a control board (such as the
) on a BBU3900, the USB driver creates a virtual Ethernet or serial interface. This allows the computer to communicate with the base station’s internal management system to perform tasks like: Arch Linux Forums Initial Commissioning : Configuring the site parameters before it goes live. Software Upgrades
: Transferring and installing new software packages via a direct connection if remote access is unavailable. Local Maintenance
: Using tools like LMT (Local Maintenance Terminal) to run diagnostic commands or check alarm statuses. Key Specifications & Requirements Supported Operating Systems
: Historically, these drivers support Windows XP through Windows 10 (both 32 and 64-bit). Driver Type : Often identified as the Huawei Wireless HS-USB Ethernet Adapter Hardware Interface
: The BBU3900 boards feature a physical USB port (sometimes labeled "USB" or "CLK") on the front panel. Installation & Usage Preparation Troubleshooting checklist
: Ensure the driver is installed on the local PC before connecting to the BBU. If the driver is missing, the PC may recognize the device as an "Unknown Device" or a "USB Serial Converter" without providing access. Connection
: Connect a standard USB cable from the PC to the USB port on the BBU's main control board (e.g., LMPT/UMPT). Verification
: Once connected, a new network adapter should appear in the Windows Device Manager IP Configuration
: The technician usually sets a static IP on this virtual adapter (typically in the 192.168.0.x subnet) to match the BBU's default local maintenance IP. Microsoft Learn Troubleshooting Driver Recognition : If the device is not detected, check the USB category in Device Manager to see if the host controller is functioning correctly. Incompatibility
: Some older Huawei drivers may conflict with modern Windows features like Memory Integrity
; in such cases, disabling these security features or manually deleting conflicting files may be required. Cable Issues

The driver is non-negotiable for several core tasks:
The BBU3900 USB driver is a piece of software that allows a Windows-based PC to communicate with the BBU3900’s internal maintenance port via a USB connection. Unlike network-based connections (e.g., via SSH or Telnet over Ethernet), the USB port on the BBU3900's main control board (typically the UMPT or WMPT board) provides a direct, out-of-band management channel.
