If Windows doesn't find the driver, you should get it directly from the source. Visit the official Targus Support website.

The acts as a translator. It takes generic commands from your operating system—such as "pair with these headphones" or "send this file"—and translates them into specific instructions that the Targus hardware chip can understand. Without this driver, your adapter is little more than a plastic dongle taking up a USB slot.

If the link in your instruction manual doesn't work, search the support site for ACB75AU , as users report this driver often works for model ACB10US1 on newer Windows versions.

Before installing a new driver, purge old ones to prevent conflicts.

Once on the product page, you will see a list of available downloads. Ensure you select the driver that matches your specific operating system (e.g., Windows 11 64-bit, Windows 10 32-bit, macOS). Download the file (usually a .zip or .exe file) to a location you can easily find, like your Desktop or Downloads folder.
