The USB Hub Controller is the communication interface between the PC and the MCU of the smart
card and the flash memory via USB port connection. The flash memory is available for the end-user to
use as storage. In Windows Explorer, the device is detected as a removable disk. The ACR100I is
powered from the USB port without other external power supply.
