Issue 1: "Device Manager shows a Yellow Exclamation Mark"
If you see USB-Serial Controller D with a yellow triangle, you are experiencing a code 10 error. This happens because newer Windows versions block older versions of the Prolific chip.
The Fix:
- Right-click the device in Device Manager and select Update Driver.
- Select "Browse my computer for drivers".
- Select "Let me pick from a list of available drivers on my computer".
- Uncheck "Show compatible hardware".
- Select Prolific as the manufacturer and choose the PL2303HXA version (often an older version like version 3.3.x works best).
- Click Next and the warning should disappear.
2. Official driver sources (safe downloads)
Do not download from random “driver download” websites. Use official sources:
1. Identify the chipset inside your AWM 20251 cable
Most AWM 20251 cables use one of these USB-to-serial chips: Guide: AWM 20251 Console Cable Driver Download &
- Prolific PL2303 (most common)
- Silicon Labs CP210x
- FTDI FT232
To check:
- On Windows: Plug in the cable → Open Device Manager → Look under Ports (COM & LPT).
If it shows an error or unknown device, check Other devices or the Universal Serial Bus controllers section for the VID/PID. - Use USBDeview or Zadig to see the chip ID.
Q4: Can I use the AWM 20251 cable on a Raspberry Pi or Arduino?
Yes. On Linux (including Raspberry Pi OS), CH340 and FTDI drivers are built into the kernel. You will see /dev/ttyUSB0. Install screen or minicom to connect. Right-click the device in Device Manager and select
Using the console cable
- Typical serial settings for network devices: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control (9600 8N1). Some devices use 115200.
- Use terminal programs:
- Windows: PuTTY, Tera Term, or Windows PowerShell with serial module.
- macOS/Linux: screen /dev/ttyUSB0 9600 or picocom/minicom.
