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.
