asr9xxusbconsoledrivers.zip is a driver package required to use the USB console port on Cisco ASR 900 series routers, such as the

Older enterprise network hardware relied heavily on RJ45-to-DB9 rollover cables connected to dedicated serial cards. As laptops transitioned exclusively to USB interfaces, administrators had to use third-party USB-to-Serial dongles. asr9xxusbconsoledriverszip

Unplug the USB cable, uninstall the Cisco USB driver (see Section 8), restart your PC, then repeat the installation procedure — ensuring that the driver is installed before plugging in the cable.

Connect a USB Type-A to Type-B cable from your laptop to the ASR 900 USB console port. Power on the ASR router. Expand the section in Device Manager.

While third-party mirrors exist, it is highly recommended to source these directly from the Cisco Software Central Standard Path Comprehensive Guide to Downloading and Installing Cisco ASR

Virtual COM port mappings change dynamically if you plug the cable into a different USB port on your laptop. Always double-check Device Manager to confirm the current active COM port number before launching your terminal session.

The asr9xxusbconsoledrivers.zip file provides the bridge's "blueprint," known as a . It translates the serial data from the router's command-line interface (CLI) into a format your PC's USB port can understand. When you connect a USB cable from your PC to the router's console port, this driver creates a virtual COM port on your Windows machine. Your terminal emulation software, such as PuTTY or SecureCRT, then connects to this virtual COM port to access the router's CLI.

Using asr9xxusbconsoledrivers.zip ensures that the USB console port enumerates correctly as a standard COM port (e.g., COM3 , COM5 ), allowing your terminal emulator to communicate with the router’s ROMMON and IOS XR CLI.

Before you begin:

Modern Cisco ASR 9000 series routers — including models like the ASR 9001, ASR 9006, ASR 9010, and ASR 9912 — often come with a micro-USB or USB Type-B console port alongside the traditional RJ-45 console jack. The USB console port offers a convenient, high-speed alternative for accessing the router’s bootup messages, ROMMON, and command-line interface (CLI), especially when the router is first deployed or recovering from a configuration failure.

Ensure the USB cable does not exceed 15 feet (4.5 meters) without an active extender. Check if the "EN" (Enable) LED next to the USB console port on the ASR router turns green, indicating an active hardware handshake. If youYou can specify:

When you connect your computer to the USB console port of an ASR router, the router's internal USB-to-serial converter chips (often manufactured by FTDI or TI) need to communicate with your operating system. Without this driver, your computer will flag the router as an "Unknown Device," preventing terminal emulators like PuTTY, SecureCRT, or Tera Term from establishing a command-line interface (CLI) session.
