To determine what is causing your adapter to not be detected: The operating system on your computer might not support the Plug & Play feature or may need the latest system updates. Make sure you meet the minimum system requirements for the adapter and that the latest Windows and system updates are installed on your computer. Make sure you use the latest driver for your specific adapter. The Universal Serial Bus port on the computer may be faulty. Try a different Universal Serial Bus port or Peripheral Component Interconnect slot on the computer. Check compatibility of the adapter and your USB ports. Some ports and hardware may not be backward compatible with each other (ie: if port is Universal Serial Bus 2.0 or 3.0). Try another device. If the device is not recognized this indicates an issue with your port. If it is detected, this indicates a possible driver, system, or software issue and you should ensure you have installed all Windows, hardware, drivers, and system updates. If you are using Extension cable that connects the USB adapter, try to connect the adapter directly to the computer without using an extension cable. If the adapter is then recognized, this is an indication the extension cable is faulty. Try restarting the computer or try the adapter on a different computer.
