Driver Download: Amsamotion Usb-cn226

The AMSAMOTION USB-CN226 is a popular, cost-effective USB-to-USB programming cable designed specifically for Mitsubishi PLCs (Programmable Logic Controllers). It acts as a direct replacement for the proprietary Mitsubishi USB cables (such as the QC30R2 or QJ71UC96 equivalents for USB connection), allowing engineers to program and monitor Mitsubishi Q, FX, and L series PLCs via a standard USB port.

If you have purchased this cable and your computer is not recognizing the device, or the programming software (GX Works2/GX Developer) cannot find the PLC, you likely need to install the specific driver.

Below is the driver download link and a step-by-step installation guide.

  • Loopback test: Connect TX to RX pins on the device and verify characters echo back.
  • Use vendor utility/firmware tools if provided to verify device-specific functionality.

    • Because AMSAMOTION (and similar cloned cables) often use specific chipset drivers (commonly based on the HL-340 or CH340 chipsets, or proprietary Mitsubishi emulation layers), the file is usually provided in a compressed folder.

    The Amsamotion USB-CN226 is a USB 2.0 to RS-232 serial converter. It features a DB9 male connector on one end and a standard USB-A on the other. Inside its housing lies a bridge controller chip—most commonly a clone of the Prolific PL2303 or a CH340 variant.

    Because Amsamotion does not maintain a public, centralized driver database like HP or Dell, users often mistakenly download malware-ridden “driver updater” software. Do not do this. Instead, follow the official methods detailed below.

    The Amsamotion USB-CN226 is a generic adapter name. Windows/macOS/Linux drivers depend on the internal chipset, not the brand name. Loopback test: Connect TX to RX pins on

    How to identify:

  • On Linux/macOS
    Run lsusb in terminal. You’ll see something like:
    Bus 001 Device 005: ID 0bda:8153 Realtek Semiconductor Corp.
    (0bda=Realtek, 8153=RTL8153)

    • ✅ Most common chipset for this model: Realtek RTL8153 – start there.

    Windows:

    Linux:

    macOS:

    Possibly, via USB OTG and serial terminal apps like “Serial USB Terminal.” Requires CH340 driver support in the kernel (most custom ROMs support it).

    Note: follow OS-specific section for your system.

    Windows (10/11):

  • After install, reboot if prompted.
  • Confirm: Device Manager → Ports (COM & LPT) → note COM number; use that COM port in your application.

    • Linux (modern distros):

  • For persistent behavior, create a udev rule mapping device to symlink/permissions (example file /etc/udev/rules.d/99-usb-cn226.rules):
  • Reload udev rules: sudo udevadm control --reload && sudo udevadm trigger

    • macOS:
