Understanding Cisco ASR 900 Series USB Console Drivers The Cisco ASR 900 Series (including models like the ASR 901, 903, and 920) are high-performance, modular aggregation routers designed for mobile backhaul and carrier ethernet services. For network engineers and technicians, the most common way to configure these devices is through a console connection. While traditional RJ-45 console ports are still common, modern ASR 900 series routers feature a Mini-USB Type-B console port. To use this port, you must install specific software on your computer, often searched for as the asr9xxusbconsoledriverszip file. What are Cisco USB Console Drivers?
When you connect a Windows, Mac, or Linux machine to an ASR 900 router via the Mini-USB port, the operating system requires a driver to recognize the connection as a virtual COM port. Without this driver, your terminal emulation software (like PuTTY, Tera Term, or SecureCRT) will not be able to communicate with the router’s Command Line Interface (CLI).
The driver package essentially acts as a bridge, converting the USB signal into a serial communication format that the Cisco IOS software understands. Key Features of the ASR 900 USB Console Connection
The USB console port offers several advantages over the older RJ-45 "rollover" cables:
Convenience: Most modern laptops no longer have serial ports, and many users prefer not to carry USB-to-Serial adapters. A standard Mini-USB cable is all that is required.
Dual-Port Support: Most ASR 9xx routers have both an RJ-45 and a USB console port. Note that the USB port takes precedence; if both are plugged in, the USB port will be the active management interface.
High Compatibility: The drivers provided by Cisco are designed to work across multiple versions of Windows and macOS. Where to Find and Download the Drivers
The official name for the file many technicians search for as asr9xxusbconsoledriverszip is actually the Cisco USB Console Software.
To download the official, safe version, you should always go to the Cisco Software Central website: Navigate to the Cisco Support & Downloads page. Search for "USB Console Software."
Choose the version appropriate for your operating system (e.g., Windows 10, Windows 11, or macOS).
You will typically download a .zip or .exe file containing the setup wizard.
Avoid downloading these drivers from third-party "driver update" websites. These files can often contain malware or outdated versions that may cause system instability or connection drops during critical configuration tasks. How to Install the ASR 9xx USB Console Drivers
The installation process is straightforward but requires administrative privileges on your computer. For Windows Users: Extract the contents of the downloaded .zip file. Run the setup.exe file. Follow the on-screen prompts to complete the installation.
Once finished, connect your Mini-USB cable from your laptop to the ASR 9xx router.
Open Device Manager and look under "Ports (COM & LPT)" to identify which COM port has been assigned to the Cisco USB console. For macOS Users: Open the downloaded .dmg file. Run the installer package.
You may need to grant permission in "Security & Privacy" settings for the driver to load.
Use the terminal command ls /dev/tty.* to find the device path for your serial software. Common Troubleshooting Tips
If you have installed the drivers but cannot connect to your ASR 900 router, check the following:
Cable Quality: Not all Mini-USB cables are created equal. Some are "charge-only" and do not have the data lines necessary for console communication. Always use a high-quality data cable.
Port Priority: Ensure nothing is interfering with the physical connection. If the router doesn't "see" the USB connection, it may default back to the RJ-45 port.
Terminal Settings: Even with the correct driver, your software must be configured correctly. The standard settings for Cisco ASR routers are: Baud Rate: 9600 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None
Driver Conflicts: If you have old USB-to-Serial drivers installed (such as Prolific or FTDI), they can occasionally conflict. Ensure the Cisco driver is the one being utilized by the specific port. Conclusion
The asr9xxusbconsoledriverszip is an essential tool for any network professional working with Cisco’s aggregation services routers. By ensuring you have the official Cisco USB console drivers installed, you can simplify your workflow, eliminate the need for bulky adapters, and maintain a reliable connection to your hardware for staging, configuration, and troubleshooting. Always keep a copy of these drivers on your technician’s toolkit drive to ensure you are prepared for field deployments.
The asr9xxusbconsoledriverszip is useful only if:
For most modern systems, skip it and use the OS’s built‑in or chip manufacturer’s driver. If you do need it, get it directly from Cisco.
The file asr-9xx_usbconsole_drivers.zip is a critical software package for network engineers working with the Cisco ASR 900 series routers, including the ASR 901, ASR 903, and ASR 920. It contains the specific USB-to-serial device drivers required to establish a console connection via the mini-USB or USB-A console ports found on these devices. Driver Overview
Unlike standard console connections that use an RJ-45 to DB-9 cable, modern ASR 900 series routers often feature a USB console port. To use this port with a Windows-based PC, you must install the Cisco Virtual COM driver provided in this zip file.
Supported Operating Systems: Windows XP, Vista, 7, 8, and 10 (32-bit and 64-bit).
