If you get Code 10 (This device cannot start) after installing the latest driver, your chip is a clone. Solutions:
Option A: Use a legacy driver (Windows 10/11)
Option B: Modify the latest driver (Advanced)
Option C: Use a different chipset adapter – Consider switching to an FTDI-based or CH340 adapter, which have better clone support.

Apple removed built-in PL2303 drivers after macOS Catalina. Here’s the fix:
Clone warning: Most MQ-U350 cables fail on modern macOS. Consider a CH340 based adapter instead.
A: No. The Windows 10 driver (CH341SER.EXE version 3.8 or newer) works perfectly on Windows 11.
Before downloading any software, you must identify the chipset inside your MQ-U350. Most issues arise from using the wrong driver version. If you get Code 10 (This device cannot

For macOS / Linux:
Critical Note: Many budget MQ-U350 cables use counterfeit chips. Prolific’s official drivers (v3.8 and above) deliberately disable these clones by triggering a “Code 10” error. You will need a legacy or patched driver.

Steps for Windows:
Flip the MQ-U350 module over. Look for a small black square IC (integrated circuit). Write down the numbers printed on it. Common chips include:
Below are the direct, trusted sources for drivers and utilities. Never download drivers from random “driver download” websites. Always use manufacturer or chipset vendor links.
