Hi-Speed USB-USB Network Adapter Driver

The Hi-Speed USB-USB Network Adapter driver allows Windows to recognize and communicate with Prolific’s USB-to-USB networking adapter. It is intended for users setting up a compatible USB network connection between computers, reinstalling Windows, or troubleshooting an adapter that appears as an unknown device.

Key Features

• Device recognition: Helps Windows identify the Prolific Hi-Speed USB-USB Network Adapter and make its network functions available.
• USB networking support: Enables the operating system to work with the adapter for a direct connection between compatible computers, subject to the required network configuration.
• Legacy Windows compatibility: Supports Windows 10, 8.1, 7, Vista, and XP when you select the appropriate driver package for your system.
• Driver maintenance: Provides a way to replace a missing driver or update an existing installation with a compatible release.

How to Install Hi-Speed USB-USB Network Adapter Driver

1. Check your Windows version. Confirm your operating system and whether it uses a 32-bit or 64-bit architecture. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supported OS list provided for this device.
2. Choose the correct package. Before starting your Hi-Speed USB-USB Network Adapter driver download for Windows, check that the package matches your adapter model and operating system. Choose the latest version that explicitly supports your configuration.
3. Download and extract the files. Use a trusted free download source and scan the package with your security software. Extract compressed files to a folder you can easily locate.
4. Install the driver. Follow the included instructions and run the installer if one is supplied. For a manual installation, open Device Manager, locate the adapter or unknown device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, connect the adapter according to its instructions, and check Device Manager for warnings. Configure the network settings on both computers as needed; installing the driver alone may not complete the connection.

Keep the driver updated when a compatible release addresses a problem or improves support for your setup. Before you update a working installation, review any available release notes and retain the previous driver package in case you need to roll back.
