ACTScom DM Port (COM13) Driver

The ACTScom DM Port (COM13) driver helps Windows recognize and communicate with the diagnostic USB interface exposed by compatible Zte devices. You may need it if Device Manager shows an unknown device, the diagnostic port is missing, or a compatible service utility cannot connect to your hardware.

Key Features

• USB diagnostic communication: Provides the interface that compatible diagnostic or maintenance software uses to communicate with supported Zte hardware.
• COM port recognition: Helps Windows identify the device as a serial-style communication port. Although the device name includes COM13, Windows may assign a different port number.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility of the specific driver package.
• Connection troubleshooting: Installing the correct driver can resolve recognition problems caused by a missing or incompatible driver, though it will not fix faulty cables or unsupported hardware.

How to Install ACTScom DM Port (COM13) Driver

1. Check your device and Windows version. Open Device Manager and locate the Zte interface under Ports (COM & LPT), Other devices, or USB devices. Check its hardware IDs and confirm whether Windows is 32-bit or 64-bit.
2. Choose a compatible package. Before starting an ACTScom DM Port (COM13) driver download for Windows, verify that the package supports your hardware and operating system. Choose the latest version that explicitly matches your device; a free download should still come from a trusted source.
3. Prepare the files. Extract the downloaded archive if necessary. If a setup program is included, follow its instructions to install the driver. Avoid packages that require unrelated software.
4. Use Device Manager if needed. Right-click the device, select Update driver or the equivalent option on older Windows versions, and browse to the extracted driver folder. Allow Windows to select the matching driver.
5. Verify the connection. Restart if prompted, reconnect the device, and confirm that its port appears without a warning icon. Select the assigned COM port in your compatible diagnostic application.

Keep the driver updated when a compatible release addresses connection issues or improves stability. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Before any update, retain a copy of the working driver so you can restore it if necessary.
