The USB devices communicate with the host computer using the human interface device (HID) protocol, essentially mimicking a keyboard. [9] [failed verification – see discussion] This avoids the need for the user to install special hardware driver software in the host computer and permits application software (such as a browser) to directly access the security features of the device without ...
