Abstract:
1. A Universal Serial Bus (USB) device supporting super speed and non-super speed connections for communication with a host device, comprising: a plurality of endpoints (EPs); a non-super speed connection port connected to the host device; a super speed connection port connected to the host device; and a configuration unit, dividing the EPs to first and second groups of EPs according to a bandwidth requirement of each EP, 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 is configured to communicate with the host device at both the super speed and the non-super speed via the super speed connection and the non-super speed connection respectively.
