To establish a console connection to a Cisco ASR 900 series router using the USB console port, you typically need a specific USB-to-Serial driver
that allows your computer to recognize the router's mini-USB or micro-USB management port as a COM port. USB Console Connectivity for ASR 900 Series For many modern Cisco routers like the
, the USB console port requires a specialized driver to function correctly. Without it, terminal emulators like PuTTY or SecureCRT will often return an "Unable to open Com port" error. Cisco Community Driver Requirements
: Most ASR 9xx routers utilize a Silicon Labs or similar USB-to-UART bridge. You can typically find the official driver package on the Cisco Software Central
page under the specific router model's "USB Console Software" section. Terminal Settings
: Once the driver is installed and the port is recognized, use the following standard settings to connect:
: 115200 (Note: This is higher than the older 9600 standard) Flow Control Troubleshooting Common Issues
If you have the drivers installed but still cannot connect, consider these common community-sourced fixes: Check Device Manager
: Verify that the device appears under "Ports (COM & LPT)" without a yellow exclamation mark. If it shows an error, you may need to uninstall and let Windows reinstall the generic USB hub driver. Port Conflicts
: Ensure no other application is using the assigned COM port. Cable Quality
: Ensure you are using a data-capable USB cable; some cheaper "charging only" cables do not have the internal wiring required for data transfer. Baud Rate Mismatch
: If you see "garbled" text, it is almost always a baud rate issue. While 115200 is standard for the ASR 920, some older firmware might still use 9600.

If both the RJ-45 console port and USB port are plugged in, the USB port usually takes priority
. Unplug the RJ-45 cable to ensure the USB connection initializes. Driver Signature Error:
On Windows 10/11, if the driver fails to install, you may need to temporarily disable "Driver Signature Enforcement" or download the latest version from Cisco's "Cloud" section. 🔍 5. Verifying the Hardware
If you aren't sure which router model you have, you can check the physical chassis for these identifiers: Compact, fixed configuration. ASR 903/907:
Modular chassis with removable Route Switch Processors (RSPs). To help you get the exact file you need, could you tell me: operating system are you using (Windows 11, macOS, Linux)? Are you seeing a specific error in your Device Manager (like "Unknown Device")? Do you have a Cisco Connection Online (CCO) account to access official downloads?
I can provide direct links to the official Cisco documentation if you can confirm your OS!
It looks like you're searching for console drivers for the Cisco ASR 900 series routers (like the ASR 901, 903, or 920). While "hot" links on third-party sites can be tempting, they often carry security risks.
Here is a quick guide on how to get the official drivers and set up your connection safely. Why You Need the Driver
Cisco ASR 900 series routers feature a USB console port (typically Mini-B). Unlike a standard RS-232 serial port, your computer requires a specific USB-to-Serial driver to recognize the device as a COM port. Without it, your terminal emulator (like PuTTY or Tera Term) won't see the router. Where to Download (The Safe Way)
The file you are likely looking for is the Cisco Windows USB Console Driver. Official Cisco Software Central: Always go to cisco.com. Search: Look for "USB Console Software."
Filenames: You are looking for versions like Cisco_usbconsole_driver_3_1.zip (or newer).
Note: You may need a free Cisco.com login to download it, but it ensures you aren't downloading malware bundled in a "hot" zip file from an unverified source. How to Install and Connect Once you have the .zip file:
Extract the folder and run the setup.exe (or the x64 version for 64-bit Windows).
Connect your USB cable to the ASR 9xx Mini-USB port and your laptop.
Check Device Manager: Look under "Ports (COM & LPT)" for Cisco USB Console Windows Driver. Note the COM port number (e.g., COM3). Terminal Settings: Baud Rate: 9600 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None Troubleshooting
Conflict: If you have both the RJ45 console and USB console plugged in, the USB port usually takes priority on ASR routers.
Driver Not Found: If Windows doesn't see the device, try a different USB cable. Some cables are "power only" and don't carry data.
Windows 10/11: Recent versions of Windows often pull a generic driver automatically, but the official Cisco driver is still recommended for stability on ASR hardware. To establish a console connection to a Cisco

While traditional Cisco devices use an RJ-45 "Rollover" cable for console access, modern ASR 900 routers feature a USB Type-A or Mini-USB console port. To use this port, your computer requires specific USB-to-UART bridge drivers—packaged as asr9xxusbconsoledrivers.zip—to recognize the router as a valid COM port in Device Manager. Key Technical Specifications
Default Baud Rate: For the ASR 920 series, the standard console speed is 115200 bps. This is significantly faster than the 9600 bps typical of older Cisco switches.
Port Location: On an ASR 920, the USB console port is typically located on the bottom right of the unit, while the standard RJ-45 console port is on the bottom left.
OS Support: The driver package includes support for Windows (32-bit and 64-bit), macOS, and Linux. Quick Setup Guide
Driver Acquisition: Download the driver directly from the Cisco Support portal. Malware Infection : The file may contain malware,
Connection: Connect a standard USB cable from your PC to the "USB Console" port on the ASR router.
Verification: Open Device Manager on Windows and look under "Ports (COM & LPT)" for USB UART to identify the assigned COM port number.
Terminal Settings: Use a client like PuTTY with these parameters: Connection Type: Serial Serial Line: [Assigned COM Port] Speed (Baud): 115200 (or 9600 for some older firmware) Data bits: 8 / Stop bits: 1 / Parity: None Troubleshooting Tip
If the port does not appear in Device Manager, ensure you are not using a "power-only" USB charging cable. The cable must support data transfer to facilitate the serial bridge. ASR920 and USB Console - Cisco Community
