Motorola Diagnostics Interface C24 (COM19) Driver

The Motorola Diagnostics Interface C24 (COM19) driver helps Windows recognize the device’s USB diagnostic interface and make it available to compatible service software through a COM port. It is intended for users who need diagnostic connectivity or are troubleshooting an unrecognized Motorola interface in Device Manager.

Key Features

• USB interface recognition: Helps Windows identify the diagnostic connection rather than leaving it listed as an unknown device.
• COM-port access: Allows compatible diagnostic utilities to communicate with the interface through its assigned serial port. COM19 is the current port designation and may differ after reconnecting or reinstalling the device.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows release and system architecture.
• Driver identification: The supplied vendor listing is Qualcomm Atheros. Confirm the device’s hardware IDs against the driver package before installation, rather than relying on the device name alone.

How to Install Motorola Diagnostics Interface C24 (COM19) Driver

1. Check your Windows configuration. Identify your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
2. Verify the package. Before starting your Motorola Diagnostics Interface C24 (COM19) driver download for Windows, compare the package’s supported hardware IDs and operating systems with your device. If offered as a free download, check its source and digital signature before running it.
3. Prepare the connection. Connect the device with a reliable USB data cable and enable its diagnostic interface if required by the manufacturer’s instructions. Extract the downloaded archive if necessary.
4. Install the driver. Run the included installer, or open Device Manager, right-click the relevant interface, select Update driver, and browse to the extracted driver folder. Avoid forcing installation if Windows reports that the package is incompatible.
5. Confirm recognition. Restart Windows if prompted, then check Device Manager for warning icons. In your diagnostic application, select the COM port Windows currently assigns to the interface.

Keep the driver updated when a verified release addresses a connection problem or adds support you need. Before you update, confirm that the latest version still supports your device and operating system; a newer package is not automatically the right match for older hardware.
