Cisco USB Console Driver 3.1 is a legacy software utility released in January 2010
that allows modern computers to communicate with Cisco networking devices via a USB Type-B
port. It serves as a virtual COM port bridge, enabling terminal emulation software like PuTTY or SecureCRT to access the device's Command Line Interface (CLI) without needing a traditional RS-232 serial adapter. Key Specifications & Compatibility Release Date: January 20, 2010. File Name: Cisco_usbconsole_driver_3_1.zip (approx. 14.6 MB). Standard Performance: Supports baud rates up to 115,200 bps
, though the default for most Cisco console ports remains 9600 baud. Operating Systems: Officially Supported:
Windows 2000, XP (32/64-bit), and Vista (32/64-bit). Older versions of Mac OS X (10.5) and various Linux distributions (Redhat, Ubuntu, Debian, Suse) also have versions available. Extended Compatibility: Many users successfully run version 3.1 on Windows 7, 8, 8.1, and 10
, though it often requires manual intervention via Device Manager. Cisco Community Supported Hardware
While often found on the download pages for specific models like the Cisco Catalyst 3560X
, this driver is universal for Cisco's ISR G2 line and various Catalyst switches: Petri IT Knowledgebase Cisco ISR G2 series (1900, 2900, 3900) and the IR1101. Catalyst 2960-S, 3560-X, 3750-X, and 3850 series. Wireless Controllers: 5500 series. Installation & Troubleshooting Tips
Tired of hunting for serial ports? Cisco’s USB Type-B console ports offer a convenient alternative to the classic RJ-45 setup. To get your laptop talking to your gear, you’ll likely need the Cisco USB Console Driver v3.1 (filename: Cisco_usbconsole_driver_3_1.zip Why use it? Convenience
: Use a standard USB-A to Mini-B cable instead of carrying proprietary rollover cables and serial adapters.
: Version 3.1 is the standard legacy release that supports a wide range of hardware, including ISR G2 routers and Catalyst switches. Plug-and-Play (Mostly)
: Once installed, your computer treats the USB connection as a standard COM port. Quick Installation Guide: : Grab the driver from the official Cisco Software Central (requires a Cisco login). (32-bit) or setup(x64).exe plugging in your cable. Device Manager and look under Ports (COM & LPT) . You should see "Cisco Virtual Com" or similar.
: Open Putty or Tera Term, select your new COM port, and set the speed to (default). Pro-Tips & Troubleshooting: Windows 10/11 Users
: If the official Cisco 3.1 driver isn't cooperating, many engineers have success using the Silicon Labs CP210x Universal Driver instead, as many Cisco devices use that underlying chipset. The "Invisible" Device
: If nothing appears in Device Manager, ensure the cable is fully seated and the device is powered on. Some 800-series routers may require a driver update for every unique port used.
The Cisco USB Console Driver 3.1 is an essential software component for network administrators and engineers who need to manage Cisco networking equipment via a direct physical connection. This driver allows your computer to recognize Cisco networking hardware—such as routers, switches, and firewalls—when connected through a USB console port rather than the traditional RJ-45 serial port. Understanding the Purpose of Version 3.1
The transition from serial to USB console ports has simplified hardware management, but it requires specific drivers to create a virtual COM port on your operating system. Version 3.1 of the Cisco USB console driver is specifically optimized for modern Windows environments. It provides the necessary interface between the hardware’s USB connector and terminal emulation software like PuTTY, Tera Term, or SecureCRT. cisco usb console driver 3.1
Without this driver, your operating system may identify the connected Cisco device as an "Unknown Device," preventing any command-line interface (CLI) access. Version 3.1 addressed several stability issues found in earlier iterations, offering better compatibility with Windows 10 and Windows 11 power management settings. Key Features and Enhancements
The 3.1 update brought several critical improvements to the deployment workflow:
Broad OS Support: It is designed to work seamlessly with both 32-bit and 64-bit versions of Windows.
Virtual COM Port Mapping: It automatically assigns a COM port number to the USB connection, which can be viewed and modified in the Windows Device Manager.
Plug-and-Play Reliability: Improved handshake protocols ensure that the connection is recognized immediately upon plugging in the USB cable.
Legacy Support: While optimized for newer gear, it maintains backward compatibility with older Cisco integrated services routers (ISR) and Catalyst switches that feature the mini-USB or USB-B console ports. Installation and Setup Guide
To successfully implement the Cisco USB Console Driver 3.1, follow these steps:
Download: Obtain the driver package (typically a .zip or .exe file) from the official Cisco Software Central portal. You will generally need a Cisco Connection Online (CCO) user account to access the download.
Pre-Installation: Ensure no Cisco devices are plugged into the USB ports before starting the installer.
Execution: Run the setup file as an administrator. Follow the wizard prompts to install the files to your local directory.
Hardware Connection: Once the installation is complete, connect your USB cable from your PC to the "Console" USB port on the Cisco device.
Verification: Open the Windows Device Manager and look under "Ports (COM & LPT)." You should see an entry labeled "Cisco USB Console Windows Driver." Note the COM port number (e.g., COM3). Troubleshooting Common Issues
If you encounter issues after installing version 3.1, consider the following solutions:
Driver Not Recognized: If the device still appears as unknown, right-click the device in Device Manager, select "Update Driver," and manually point the search to the folder where you installed the Cisco driver.
Port Conflicts: If your terminal emulator cannot open the port, ensure no other application is using that specific COM port. You can change the port assignment in the Advanced Settings of the driver properties.
Cable Quality: USB console connections are sensitive to cable length and shielding. Always use a high-quality USB 2.0 or 3.0 cable under 5 meters to avoid data corruption or signal loss during firmware upgrades. Conclusion Cisco USB Console Driver 3

Q: How do I use the Cisco USB Console Driver 3.1? A: Connect the USB cable, launch a terminal emulator program, select the COM port, configure the connection settings, and establish the connection.
Q: What are some common issues with the Cisco USB Console Driver 3.1? A: Common issues include driver not recognized, connection issues, and device not detected. These issues can be resolved by checking the installation, COM port settings, and device connection.
"The driver installed, but I can't connect." This is the most common issue. Just because the driver is installed doesn't mean your terminal software knows which port to use.
"My terminal shows gibberish." Remember, the USB console port uses the same settings as the standard RJ-45 console port.
"It works, then disconnects randomly." Check your USB cable. Cheap micro-USB cables often have loose connections. The Cisco-branded flat cables are generally the most reliable.
If you are managing Cisco networking gear, you know the frustration of legacy DB-9 serial cables. The USB Console cable is a massive upgrade—until you plug it into a modern laptop and realize it isn't recognized.
