Qualcomm HS-USB Diagnostics 9025 (COM17) Driver

The Qualcomm HS-USB Diagnostics 9025 (COM17) driver lets Windows recognize the diagnostic USB interface exposed by compatible Qualcomm-based devices and make it available to supported service tools. Listed under Qualcomm Atheros in the USB category, this driver is intended for technicians, developers, and users who need diagnostic communication rather than ordinary USB file transfers.

Key Features

• Diagnostic interface support: Allows compatible diagnostic software to communicate with the device through its USB serial interface.
• Device Manager identification: Helps Windows identify the diagnostic port instead of leaving it listed as an unknown device or an interface with a missing driver.
• COM-port access: Makes the interface available as a serial port. COM17 is the current port assignment; Windows may assign a different number after reconnection or installation on another computer.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for the correct Windows release and 32-bit or 64-bit architecture.

How to Install Qualcomm HS-USB Diagnostics 9025 (COM17) Driver

1. Check your system and device. Confirm your Windows version and architecture, then open Device Manager to inspect the device’s hardware IDs. Match these against the driver package’s supported devices.
2. Choose a compatible package. Before starting a Qualcomm HS-USB Diagnostics 9025 (COM17) driver download for Windows, review its compatibility information and source. A free download should still come from a trusted provider and include a valid signature where required.
3. Extract and install. If the package includes an installer, follow its instructions. Otherwise, extract the files, right-click the diagnostic interface in Device Manager, select Update driver, and browse to the extracted folder.
4. Reconnect and verify. Restart Windows if prompted, reconnect the device, and check that the diagnostic interface appears without a warning icon. Select its assigned COM port in your compatible diagnostic application.
5. Address compatibility issues carefully. For Windows 10/11 systems, do not assume the same package supports both versions: Windows 11 is not included in the listed support. Use a verified compatible driver rather than disabling driver-signature checks.

Keep the driver updated when a verified release addresses a connection problem or improves compatibility with your diagnostic tools. Choose the latest version that explicitly supports your hardware and operating system, and retain the previous working package in case you need to roll back an update.
