A method for resetting and reenumerating a Universal Serial Bus device, an Electrical Fast TransientBurst unit of a USB device for resetting and reenumerating the USB device and a USB device are described. In one embodiment, first and second channel plates are provided and are sealingly connected to a test chip in consecutive steps. An entry position correspondent to a stack position pointed to by the entry designation unit is adopted as a subroutine callreturn prediction address and consequently the prediction of the subroutine return address becomes more accurate and the processing speed becomes higher.
