Asr-9xx Usbconsole Drivers.zip

Getting Started with the Cisco ASR-9xx USB Console If you’ve recently unboxed a Cisco ASR 900 series router (like the ASR 920), you might have noticed a USB port labeled for console access. Unlike the traditional RJ45 ports that require a "blue" rollover cable, this USB serial port allows you to connect directly from your laptop's USB port.

However, there is one catch: your computer won't recognize the device until you install the specific asr-9xx_usbconsole_drivers.zip What is the ASR-9xx USB Console Driver?

This driver package contains the necessary files to create a Virtual COM Port

on your Windows, Mac, or Linux machine. Without it, your terminal emulation software (like PuTTY or TeraTerm) won't be able to "see" the router as a valid serial destination. Quick Installation Guide (Windows)

Follow these steps to get your console connection up and running: Download the Driver : Visit the Cisco Software Download site. You will typically find it under the USB Console Software category for your specific router model.

Note: A valid Cisco.com account is required to download these files. Extract the Files : Unzip the asr-9xx_usbconsole_drivers.zip folder on your desktop. Run the Installer For 64-bit systems: Run setup(x64).exe For 32-bit systems: Run Connect the Hardware Type-A to Type-A USB cable to connect your laptop to the ASR's USB console port. Verify the Port Device Manager on your PC. Under Ports (COM & LPT)

, you should see "Cisco Virtual Com" with an assigned COM port number (e.g., COM3). Troubleshooting Common Issues Connection Failed : Ensure you install the driver Asr-9xx Usbconsole Drivers.zip

plugging in the USB cable, or the hardware might be incorrectly identified by Windows. Mutually Exclusive Ports

: On many ASR 900 models, the USB console and the RJ45 console port cannot be used at the same time; the USB port usually takes precedence when a cable is detected. Driver Not Found

: If the automatic installer fails, you can manually update the driver in Device Manager by pointing it to the extracted folder from your Recommended Terminal Settings

The file "Asr-9xx Usbconsole Drivers.zip" is a critical software package for network administrators managing Cisco ASR 900 Series aggregation services routers (specifically models like the ASR 902, 903, and 920).

The primary "good feature" of this driver is that it enables a direct management connection between a modern laptop and the router via a USB Type-A to Type-A cable, eliminating the need for traditional serial adapters or specialized rollover cables. Key Features & Benefits Getting Started with the Cisco ASR-9xx USB Console

Virtual COM Port Creation: Once installed, the driver allows your computer to recognize the router's USB console port as a standard USB UART or Virtual COM port.

Plug-and-Play Management: It allows for easy out-of-band management using standard terminal emulators like PuTTY or SecureCRT.

Broad OS Compatibility: The drivers are typically designed for Windows (including Windows 10/11), though the zip package specifically provides the executable installers (e.g., xrusbser_ver2100_installer.exe) required for the operating system to interface with the router's internal USB-to-Serial converter.

High-Speed Data Transfer: While the default console speed is often 9600 baud, these drivers support asynchronous terminal connections at rates up to 115,200 baud for faster log output and configuration transfers. Usage Details ASR920 and USB Console - Cisco Community

Step 2: Extract and Manually Install

  1. Extract Asr-9xx Usbconsole Drivers.zip to C:\ASR_Drivers.
  2. Open Device Manager (Win+X → M).
  3. Locate the ASR-9xx device – it will appear under Other devices as “ASR USB Console” with a yellow triangle.
  4. Right-click → Update driver → Browse my computer for drivers.
  5. Navigate to C:\ASR_Drivers and check “Include subfolders.”
  6. Click Next. If a security warning appears, select Install this driver software anyway.

1. Understanding the ASR-9XX USB Console Interface

Before downloading any drivers, it’s essential to understand the hardware. Unlike legacy console ports that used a DB-9 serial connector, modern ASR-9xx routers have moved to a USB Mini-B or USB Micro-B console port (depending on the model).

1.3 Key Features Enabled by the Driver

Without this driver, the operating system may recognize the device as an “Unknown USB Device (Device Descriptor Request Failed)” or load a generic serial driver that only exposes a single, corrupted port. Extract Asr-9xx Usbconsole Drivers

Critical Files Explained:

Issue 2: Console shows gibberish (�符号乱码)

Cause: Baud rate mismatch.
Fix: The ASR-9xx might have been changed to 115200 baud. Try standard rates: 9600, 19200, 38400, 115200. Also disable hardware flow control.

A. Windows Installation (7, 8, 10, 11)

Prerequisites: Administrator rights, disabled driver signature enforcement (for older unsigned drivers).

  1. Download and extract Asr-9xx Usbconsole Drivers.zip to a folder like C:\ASR9xx_Drivers.
  2. Plug the USB cable into the ASR-9xx router (router powered on) and your PC.
  3. Open Device Manager (Win+X → M). Look for a yellow-bang “Unknown Device” or “CP210x” under Other devices.
  4. Right-click → Update driver → Browse my computer for drivers.
  5. Navigate to C:\ASR9xx_Drivers\Windows\CP210x_Windows_Driver.
  6. Click Next. If Windows warns about an unsigned driver, select “Install anyway”.
  7. Success: The device will appear under Ports (COM & LPT) as “Silicon Labs CP210x USB to UART Bridge (COMx)”.
  8. Launch your terminal emulator (PuTTY, SecureCRT, or minicom). Set:
    • Baud rate: 9600 (default, though some models use 115200)
    • Data bits: 8
    • Parity: None
    • Stop bits: 1
    • Flow control: None

Note for Windows 10/11: Microsoft’s inbox driver sometimes auto-installs a generic CDC driver that fails. You must manually force the SILabs driver.
