Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:

Windows may install drivers for select devices, say the graphics card, under certain circumstances. This happens by default for instance when the device is setup, but may also happen when Microsoft pushes driver updates through Windows Updates.

1. The drivers stores the offsets, and since the IRQ handler knows for which port and FIFO it is called it can add the hardware filter nr (which are independed for each port and FIFO) to the stored offset, and use that to index the mapping array and find the correct callback.
2. The Zephyr kernel scheduler enables high precision synchronization to a cellular network. For IoT devices, power efficiency is crucial and the Zephyr OS comes prepared to support this demand, resulting in ultra-low power consumption and long battery life. Driver API and subsystems add scalability to the solution.
