There is also a sample for receiving a standard HID USB keyboard connection. You can see an sample of doing that for some devices in the USB Host Shield Library example.
So you create the driver with write code yourself. In the case of Arduino, there is basically no OS, no pre-installed drivers, even can't to get it from the Internet (In the first place, the driver for microcontroller is not released in many cases). Or the OS is automatically getting the driver from the internet. Many drivers are pre-installed on your PC's operating system. It is software used and prepare by the "host side" of the device. The device driver doesn't come from the connected USB device. Is it right that the microcontroller does not recognize the driver when connected to Arduino USB Host Shield 2.0? Is it because of the built-in driver that it connects to the desktop with the sound of recognition?
