Usb Console Software 3.1 - Cisco-usbconsole-driver-3-1.zip - ((top))

Key details about this specific file:

Official driver name: Cisco USB Console Driver
Version: 3.1
ZIP file name: cisco-usbconsole-driver-3-1.zip (sometimes listed as usbconsole_setup_3.1.exe after extraction)
Purpose: Allows a Windows PC to communicate with a Cisco device’s mini-USB console port via a USB cable (instead of a traditional RJ45-to-serial console cable).
Devices supported: Many Cisco routers, switches, and firewalls with a mini‑USB console port (e.g., ISR 890/1900/2900/3900 series, Catalyst 2960‑X/3560‑X/3750‑X, ASA 5500‑X, etc.).
Operating systems: Officially supports Windows 7, 8, 8.1, 10 (32/64‑bit) — may also work on Windows 11.

How to Install It (Retro Guide)

If you are maintaining legacy gear (e.g., a 2811 router or a 3750X switch) from a Windows 10 or 11 machine, here is the correct sequence:

Do not plug in the cable yet. (Windows will attempt an automatic, often failed, installation).
Extract the ZIP and run Cisco_usbconsole_driver_3_1.msi as Administrator.
Accept the UAC prompt and complete the wizard.
Reboot (Driver 3.1 requires a restart to register the serial class).
Now connect the USB mini-B cable from your PC to the router’s "CONSOLE" port.
Open Device Manager → Ports (COM & LPT). You should see "Cisco USB Console Port (COMx)".

Finally, configure PuTTY, SecureCRT, or Terminals with 115200 baud, 8 data bits, no parity, 1 stop bit (8N1), no flow control. usb console software 3.1 - cisco-usbconsole-driver-3-1.zip

The Pitfalls of Version 3.1

While functional, this driver is a decade old. Users report three common frustrations: Key details about this specific file:

Windows 10/11 Driver Signature Enforcement: Older unsigned or poorly signed drivers may be blocked. You may need to disable Secure Boot or run bcdedit /set testsigning on (not recommended for production PCs).
The "Yellow Bang": Even after install, Windows might assign the driver but show an error (Code 10 or 43). This usually requires manually updating the driver via Device Manager → "Browse my computer" → "Let me pick" → selecting "Cisco USB Console Device."
USB 3.0 vs. 3.1 Confusion: Note the "3.1" in the filename refers to the driver version, not USB 3.1 speed. This is a full-speed USB 2.0 (12 Mbps) device.

6. Uninstallation

Open Control Panel → Programs and Features.
Select Cisco USB Console Driver → Uninstall.
Alternatively, run uninstall.exe from the extracted package.
Reboot to complete removal.

Step 5: Trust the Publisher

Windows Security will prompt you to verify the publisher. Since this is a Cisco-signed driver, click Install. Official driver name: Cisco USB Console Driver Version:

The Problem:

Your operating system does not natively understand how to talk to this USB port. When you plug a USB cable from your PC into the Cisco device, Windows sees unfamiliar hardware. Without the correct driver, you see the dreaded "Unknown Device" or "FTDI" generic warning in Device Manager.
