20251 Driver — Awm

If your device uses a Prolific chip (common for AWM 20251):

If it uses an FTDI chip:

If it uses a CH340 chip:

1. Definition AWM 20251 refers to a specific Appliance Wiring Material style under UL 758. It is not an electronic component that requires a driver; it is a flexible, shielded cable used for internal wiring of electronic equipment.

2. Key Construction

3. Electrical & Thermal Ratings

4. Common Applications

5. Key Specifications (UL/CSA)


Yes, if the chipset is standard. Use the driver specific to the chip (Prolific, FTDI, CH340), not a generic "COM driver."

Could you provide any of the following?

Once you clarify, I can:


Would you like me to proceed with one of these assumptions?
For example:

Let me know.

The code AWM 20251 does not actually refer to a specific device, but rather to a UL Style number for the raw cable material. This cable type is most commonly used for Cisco Console Cables, telephone lines, and RS232-to-RJ45 adapters.

Because "AWM 20251" is just the cable, the driver you need depends entirely on the chipset inside the adapter or the laptop model you are using. 🛠️ Option 1: You are using a Cisco/Console Cable awm 20251 driver

If your AWM 20251 cable has a USB plug on one end, it likely uses a serial-to-USB converter chip. You generally need one of these two drivers:

FTDI VCP Drivers: The most common driver for high-quality console cables. You can find them on the FTDI Chip official site.

Prolific PL2303 Drivers: Common in budget cables. These can be downloaded from the Prolific Support page. 💻 Option 2: You have a Lenovo Laptop

The number 20251 is also the "Machine Type" for the Lenovo G700 Laptop. If you are looking for drivers for this specific computer: Official Source: Visit the Lenovo Support Portal.

How to find: Search for "G700 (20251)" to find drivers for your Chipset, Wi-Fi, and Graphics. 🔍 How to identify the correct driver

If neither of the above works, follow these steps to find the exact hardware ID:

Open Device Manager: Right-click the Start button and select Device Manager. If your device uses a Prolific chip (common for AWM 20251):

Find the Device: Look for "Unknown Device" or "USB-Serial Controller" (often under "Other devices" or "Ports").

Check Properties: Right-click the device > Properties > Details tab. Copy Hardware ID: Select Hardware Ids from the dropdown. Look for a string like USB\VID_xxxx&PID_xxxx.

Search that specific code online to find the exact manufacturer driver. To help you find the exact link, could you tell me: Does the cable have a USB end or a 9-pin serial end? Are you using a Lenovo G700 laptop?

What Operating System are you using (Windows 10, 11, Mac, etc.)?

Open Device Manager again. Expand "Ports (COM & LPT)". Your device should now appear as "Prolific USB-to-Serial Comm Port (COM3)" or similar, without any warning icons.

Most AWM 20251 devices work with the built-in pl2303 or ftdi_sio kernel module.

If not recognized:

sudo modprobe pl2303
sudo apt-get install linux-modules-extra-$(uname -r)

Cause: Driver conflict or outdated chipset driver. This is extremely common with Prolific clones.
Fix: Uninstall all existing COM port drivers from Device Manager, then use the Prolific Driver Fixer tool (official from Prolific) to clean old entries before reinstalling.
