Software 3.1 - Cisco-usbconsole-driver-3-1.zip | Usb Console
This software package is the official Windows driver for Cisco’s USB-to-UART (Universal Asynchronous Receiver-Transmitter) console port. Starting around 2008 with routers like the Cisco 1900, 2900, and 3900 series (ISR G2), Cisco began replacing the classic RJ45 console port with a mini-USB port labeled "CONSOLE."
When you plug a standard USB A-to-mini-B cable from your PC into that router, the device identifies itself using a specific Vendor ID (VID_0B05 for some models or similar PID values). Windows does not natively recognize this chipset (often a Silicon Labs CP210x variant). Without Driver 3.1, the router appears as an "Unknown Device" in Device Manager.
Version 3.1 was a significant update because it introduced: usb console software 3.1 - cisco-usbconsole-driver-3-1.zip
| File/Folder | Purpose |
| :--- | :--- |
| Cisco_usbconsole_driver_3_1.msi | The main Windows Installer package (64-bit/32-bit combined). |
| x64/ | Folder containing 64-bit driver files (cusbser.sys, cusbport.sys). |
| x86/ | Folder containing 32-bit driver files (for legacy Windows). |
| release_notes.txt | Engineering notes, supported OS versions, and known bugs. |
Critical Note: Version 3.1 is the last official release that supports Windows 7, 8, 8.1, 10, and 11 (up to the 22H2 builds). Cisco has since moved to a unified driver model, but many engineers swear by 3.1 for its rock-solid performance. This software package is the official Windows driver
If your query ends with “— paper”, it likely means you are documenting this filename in a written (paper) inventory, log, or change management record. In that case, you should note:
Driver: Cisco USB Console Driver v3.1
Filename:cisco-usbconsole-driver-3-1.zip
Usage: Windows installation for USB console access to Cisco gear.
Installation: Extract ZIP, runsetup.exe(orusbconsole_setup_3.1.exe), then connect the device. Critical Note : Version 3
Windows Security will prompt you to verify the publisher. Since this is a Cisco-signed driver, click Install.
Connect your PC to the Cisco device using a standard USB A-to-Mini-B or USB A-to-C cable (depending on your switch/router model). Windows will attempt to install a driver automatically; this will almost certainly fail, leading to a "Device driver software was not successfully installed" notification.
Short answer: Only for legacy hardware.
