4.2 Драйвер суурилуулах
For Windows operating systems, the adapter is designed for "Plug and Go" functionality, meaning drivers typically install automatically upon connection. For Linux and Mac OS X, built-in drivers are often available, or specific drivers may be required depending on your system version. Refer to the Coolgear website for the latest driver information if automatic installation does not occur.
4.3 Mounting Kit Installation (Optional)
The included mounting kit allows for secure installation of the adapter. The adapter slides into the bracket, which can then be affixed to a surface using screws or other appropriate fasteners. This is particularly useful for industrial or fixed installations.
