Understanding "asr9xxusbconsoledriverszip" – USB Console Drivers for Cisco ASR 9000 Series Routers
The term asr9xxusbconsoledriverszip typically refers to a compressed archive (ZIP file) containing USB console drivers for Cisco’s ASR 9000 series aggregation services routers. These drivers are essential for establishing a direct out-of-band management connection between a computer (usually a laptop or desktop) and the router’s console port via a USB-to-serial adapter or the router’s built-in USB console port.
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.
The "asr9xxusbconsoledriverszip" package typically includes:
.inf and .sys files) that allow the OS to recognize the router’s USB console as a virtual COM port.Why is this file important?
Without the correct driver, your PC will not detect the USB console connection, preventing any serial terminal access (using PuTTY, Minicom, SecureCRT, etc.). The ZIP file ensures that network engineers and administrators can quickly install the necessary driver on Windows environments, where driver signing and compatibility can be strict.
Where to find it?
This driver package is not typically included on a public download page but may be found: asr9xxusbconsoledriverszip
Best practices:
In summary, asr9xxusbconsoledriverszip is a niche but crucial file for network engineers working with Cisco ASR 9000 series hardware, enabling a reliable, low-level console connection via USB when traditional serial ports are unavailable or inconvenient.
asr9xxusbconsoledrivers.zip is a driver package required to use the USB console port on Cisco ASR 900 series routers, such as the
. On these devices, the physical USB-A port is actually a serial interface compliant with the TIA/EIA-232F standard, necessitating a specific virtual COM port driver to communicate with a PC. Driver Package Overview
: The zip file typically contains installers for various Windows versions (XP, Vista, 7, 8, 10), notably the xrusbser_ver2100_installer.exe Hardware Compatibility : Primarily used for ASR 900 series routers (
) but often compatible with other Cisco devices supporting a USB console port, such as Catalyst 3560X or 6880X switches Physical Connection : Requires a USB Type-A to Type-A asr9xx_usbconsole_drivers
cable or a special USB-to-RJ45 adapter, depending on the specific ASR model. Installation Steps for Windows
If you can’t find the official zip or it fails, identify the USB‑to‑serial chip:
VID_0403 = FTDI → download from FTDI’s site.VID_10C4 = SiLabs → download CP210x driver from Silicon Labs.Those generic drivers almost always work and are more up‑to‑date.
Open PuTTY, SecureCRT, or the Windows Terminal. Use the following settings:
COM# (e.g., COM5)960081NoneNone (or XON/XOFF if experiencing issues)Press Enter. You should now see the ASR 9000 boot prompt or the XR configuration prompt.
In the world of high-end service provider routing, few platform names command as much respect as the Cisco ASR 9000 Series. Designed for massive scale, high availability, and deep software programmability, these routers form the backbone of many ISP, data center, and enterprise WAN cores. However, before you can deploy BGP policies, MPLS segments, or segment routing, you must perform one critical, low-level task: establish console access. Windows USB drivers (
Modern ASR 9000 routers (including the ASR 9001, ASR 9006, ASR 9010, and ASR 9912) no longer rely solely on classic RJ45 console ports. Instead, they feature a USB console port (often labeled CONSOLE USB or USB CONSOLE). To make this port work with your laptop or terminal server, you need the correct device drivers. This is where the cryptic yet essential filename asr9xxusbconsoledriverszip enters the scene.
This article unpacks everything you need to know about this driver package—what it is, where to find it, how to install it, and how to troubleshoot common issues.
Regardless of your OS, the serial parameters are identical for Cisco ASR 9000 USB console:
| Parameter | Value | |------------------|-----------------| | Baud rate | 115200 | | Data bits | 8 | | Parity | None | | Stop bits | 1 | | Flow control | None |
Example using PuTTY (Windows):
COM5 (adjust to your system)115200Once connected, press Enter a few times. You should see the router prompt (e.g., RP/0/RP0/CPU0:ASR9000#). If not, verify power and cable integrity.
