Hisense HS-USB Diagnostics 9004 (COM6) Driver

The Hisense HS-USB Diagnostics 9004 (COM6) driver helps Windows recognize the diagnostic USB interface exposed by a compatible Hisense device and makes it available to supported service software. It is intended for users or technicians who need a diagnostic connection, particularly when Device Manager shows an unrecognized device or a warning beside the port.

Key Features

• Diagnostic USB communication: Enables compatible diagnostic tools to communicate with the Hisense device through its USB diagnostic interface.
• COM port recognition: Helps Windows identify the diagnostic serial port. Although the device name includes COM6, Windows may assign a different port number depending on your system.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches both your Windows version and its 32-bit or 64-bit architecture.
• Device identification: A correctly matched driver can resolve recognition problems caused by a missing or incompatible driver, allowing supported service applications to access the interface.

How to Install Hisense HS-USB Diagnostics 9004 (COM6) Driver

1. Check compatibility. Open Device Manager and locate the Hisense diagnostic interface, which may appear under Ports (COM & LPT) or Other devices. Check its hardware IDs in Properties to confirm that the driver package matches.
2. Select the correct package. Before starting your Hisense HS-USB Diagnostics 9004 (COM6) driver download for Windows, verify the supported operating systems and architecture. If comparing Windows 10/11 packages, note that Windows 11 is not included in the listed support information.
3. Download and extract. Obtain the driver from a trusted source and extract the archive if necessary. A free download should still be checked for authenticity and a valid digital signature.
4. Install the driver. Run the supplied installer, if available, or right-click the device in Device Manager, choose Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing Windows security warnings.
5. Verify the connection. Reconnect the device and restart Windows if prompted. Confirm that the diagnostic interface appears without a warning icon, then select its assigned COM port in your compatible diagnostic software.

Keep the driver updated when a compatible release addresses connection issues or improves support for your system. Check the latest version against your device’s hardware IDs before you update; a newer package is not automatically the right match. If your diagnostic connection works reliably, avoid replacing the driver with an unverified alternative.
