K-Touch 1xEV-DO Diagnostics Interface (COM29) Driver

The K-Touch 1xEV-DO Diagnostics Interface (COM29) driver lets Windows recognize the diagnostic USB interface on compatible K-Touch devices from Beijing Tianyu Communication Equipment. It is intended for users who need a working diagnostic COM port for compatible servicing or troubleshooting software, particularly when the interface appears as an unknown device in Device Manager.

Key Features

• USB interface recognition: Helps Windows identify the connected K-Touch diagnostic interface rather than leaving it listed as an unrecognized USB device.
• Diagnostic communication: Provides the serial-port connection that compatible diagnostic software uses to communicate with the device.
• COM port access: Allows diagnostic tools to select the interface through a Windows COM port. Although this device is labeled COM29, the assigned port number may vary between computers.
• Legacy Windows support: Listed supported systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.

How to Install K-Touch 1xEV-DO Diagnostics Interface (COM29) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the interface’s hardware IDs to help verify that the driver package matches your connected device.
2. Select the appropriate package. Before starting your K-Touch 1xEV-DO Diagnostics Interface (COM29) driver download for Windows, review its compatibility information. If a free download is offered, verify its source and avoid unrelated installers.
3. Extract and install the driver. Unpack the downloaded archive if necessary. Run the included setup program, or open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder. Menu wording varies by Windows version.
4. Reconnect and verify. Follow any restart prompts, then reconnect the device using a reliable USB cable. Check that the diagnostic interface appears without a warning icon, typically under Ports (COM & LPT).
5. Configure your diagnostic software. Select the COM port shown in Device Manager. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the listed supported operating systems; do not assume the package supports it.

Keep the driver updated when a verified, compatible release addresses recognition or communication problems. Check the latest version against your hardware and operating system before you update, and retain a working driver package in case you need to restore the previous installation.
