Once you have identified the internal chipset using the hardware IDs, download and install the official driver from the respective manufacturer. Option A: FTDI Chipset Drivers (Recommended)
Solution 3: Check your terminal configuration to confirm that is completely disabled. Conclusion
(Not a Model Number)
Download the driver executable for your operating system Architecture (e.g., Windows x64 setup executable). Disconnect your console cable. Awm 20251 Console Cable Driver
Cisco does not provide a universal driver. Instead, their console cables use either the Silicon Labs CP210x (most common) or FTDI chips. Download the respective driver from Silicon Labs or FTDI. For older Cisco products with a USB mini‑B console port, you may need the Cisco USB console driver from the Cisco Software Download portal.
: It is often recommended to install the driver software before plugging in the cable to ensure the OS correctly binds the hardware to the COM port.
Found in premium, highly reliable console cables. They utilize chipsets like the FT232R or FT232H. FTDI drivers are generally robust and natively supported across most enterprise OS platforms. Once you have identified the internal chipset using

Visit the official FTDI Chip VCP (Virtual COM Port) Drivers page.
If your terminal window opens but displays unreadable symbols, shapes, or blank lines, the driver is working perfectly, but your serial settings are misconfigured. Close the session and verify that your Baud Rate matches the specific requirements of your networking hardware. Disconnect your console cable
Serial (paid software), Minicom, or the native screen command utility in the Terminal. Standard Serial Settings
Try plugging the cable into a different physical USB port—ideally a USB 2.0 port instead of a USB 3.0 port, as older serial chipsets occasionally struggle with newer USB controller power handshakes. Avoid using unpowered external USB hubs. Garbage Characters or Corrupted Text on Screen
An AWM 20251 console cable is a physical lifesaver when configuring network infrastructure, but the wire itself tells only half the story. By looking up the hardware Vendor ID (VID) in your Device Manager, you can bypass the ambiguity of the cable jacket label, target the correct underlying controller chipset (FTDI, Prolific, or CH340), and install the stable driver required to secure a reliable terminal session. If you need help getting your cable running, tell me: What are you using? What is the Hardware ID (VID/PID) listed in Device Manager?
Because the text on the jacket only describes the copper and plastic housing, installing a driver based purely on the string "AWM 20251" is impossible. To get the cable working, you must identify the internal USB-to-Serial converter chipset embedded inside the cable’s USB connector head. The Core Chipsets Inside Your Cable
