It should recognize it if you've installed the drivers.

On Windows, we use the HID driver. On MacOS/Linux, we are able to communicate with the Phidgets directly from userspace (using the phidget21 library).

It uses USB.

I'm not sure that I understand the point of your question?

Communication from 8/8/8 to your application goes throughout these levels:

8/8/8/-> USB Cable -> USB Host controller in your PC -> USB Host controller driver in the kernel -> USB HID driver in the kernel -> Phidgets C library in userspace -> higher level library depending on your API of choice (Java/.NET/COM/AS3.0/Python/C/Phidget Webservice/etc.). -> your Application

USB is not like the traditional serial bus where you can directly control the signal on the wires from your application, all communication goes through the host controller driver.
