Input the correct COM port and use the following standard Cisco serial settings: 9600 Data bits: 8 Parity: None Stop bits: 1 Flow control: None ❌ Troubleshooting Common Driver Issues
The Cisco USB Console Driver is a utility software required to establish a connection between a management workstation (PC or Laptop) and a Cisco network device (such as a switch or router) via a USB Type-A or USB Type-C console port. This driver allows the computer to recognize the Cisco device as a virtual COM port, enabling the use of terminal emulation software like PuTTY, TeraTerm, or SecureCRT.
After the driver is successfully installed, the device will appear under 'Ports (COM & LPT)' in Device Manager as 'Cisco Serial (COMx)', where 'x' is the COM port number assigned by Windows. You can then use a terminal emulator like PuTTY or Tera Term to connect to the device with these exact serial configuration settings: usb console software 31 ciscousbconsoledriver31zip hot
Version 3.1 is considered legacy software. If you are running newer operating systems (such as Windows 11) or managing newer Cisco hardware, it is highly recommended to check the official Cisco support website for Cisco USB Console Driver Version 3.5 or newer to ensure full compatibility and stability.
If you are encountering specific errors with this driver or need to know how to set up for a USB console connection , let me know. I can also provide a list of common terminal settings (baud rate, parity, etc.) for Cisco equipment . Input the correct COM port and use the
Extract ciscousbconsoledriver31zip to a known folder (e.g., C:\CiscoDriver ).
Point to the folder where you extracted the files in Step 1. You can then use a terminal emulator like
Windows may default to a generic "USB Serial Port" (Cypress) driver instead of the specific "Cisco Serial" driver.
It is the official, stable driver for older Cisco ISR-G2 routers and earlier Firepower appliances.
This error in PuTTY or Tera Term usually means the COM port is already in use by another program.
