The ITE driver package identified by af9035hb.inf helps Windows recognize compatible hardware and install the components needed for communication with the device. Because af9035hb.inf is an installation information file rather than a GPU model name, confirm that the download matches your hardware ID before installing it on Windows 11, 10, 8, or 7.

Key Features

• Hardware identification: Provides Windows with installation details used to associate the driver package with matching ITE hardware.
• Device communication: Installs the associated driver components that allow Windows and compatible software to interact with the device.
• Device Manager integration: Helps Windows configure supported hardware, which may resolve an unrecognized-device entry when a missing or incorrect driver is the cause.
• INF-based installation: Supports manual driver selection through Device Manager when the complete package includes af9035hb.inf and its required supporting files.

How to Install

1. Confirm the hardware match. Open Device Manager, right-click the device, and select Properties. Under Details, choose Hardware Ids and compare the displayed values with those supported by the driver package. Do not rely on the GPU category label alone.

1. Choose the appropriate package. Check that the download explicitly supports your version of Windows 11, 10, 8, or 7 and your system architecture. An INF filename alone does not establish compatibility with every Windows release.

1. Extract the download. If the package is compressed, extract it to a local folder. Keep af9035hb.inf together with all accompanying files; the INF contains installation instructions, not the complete driver itself.

1. Install the driver. Use the included setup program if one is provided. Otherwise, right-click the matching device in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder.

1. Check the result. Restart if prompted, then return to Device Manager to confirm that the device appears without a warning symbol. Test it with the appropriate software. If Windows reports an incompatible or unsigned driver, stop and obtain a suitable signed package rather than disabling security checks.

Common Issues and Fixes

• Install fails or Windows blocks the driver: Run the installer as administrator and match the package to Windows x86/x64. If the AF9035 DVB-T USB tuner package is unsigned/legacy, temporarily disable driver signature enforcement, install, then re-enable it.
• Device not detected / Code 10 or 43: Connect the tuner directly to a rear USB 2.0 port, not a hub. In Device Manager, remove hidden devices, scan for hardware changes, and check whether the AF9035 tuner appears under Universal Serial Bus devices or Sound, video and game controllers.
• Version conflicts after an update: Uninstall the old ITE/Afatech driver and select “Delete the driver software,” reboot, then install the matching `af9035hb.inf` package. Avoid mixing vendor driver packs; use Device Manager to confirm the installed driver version and roll back if tuning breaks.
