Abstract:
Universal Serial Bus (USB) devices supporting super speed and non-super speed connections for communication with a host device includes a plurality of endpoints (EPs), a non-super speed connection port, a super speed connection port and a configuration unit. The non-super speed connection port and the super speed connection port are connected to the host device. The configuration unit is arranged for dividing the EPs to first and second groups of EPs according to a bandwidth requirement, determining whether a super speed connection with the host device is successfully established and configuring the first group of EPs to operate at a super speed and configuring the second group of EPs to operate at a non-super speed when the super speed connection with the host device is successfully established such that the USB device communicates with the host device at both the super speed and the non-super speed.
