EFTB unit, USB device with the EFTB unit and method for resetting and reenumerating the USB device
Abstract:
A method for resetting and reenumerating a Universal Serial Bus (USB) device, an Electrical Fast Transient/Burst (EFTB) unit of a USB device for resetting and reenumerating the USB device and a USB device are described. In one embodiment, a method for resetting and reenumerating a USB device involves detecting a USB reset command from a host device at a USB device, setting a reset flag in the USB device in response to the detecting of the USB reset command, determining if the USB device is in a corrupted state in response to the reset flag, and causing a Single Ended Zero (SE0) signal to be issued to reset the USB device out of the corrupted state and reenumerate the USB device back to the host device if the USB device is determined to be in the corrupted state. Other embodiments are also described.
Abstract(Chinese):

描述了用于复位和重新计数USB设备的USB快速瞬态/突发（EFTB）单元的通用串行总线（USB）设备的复位和重新计数的方法，用于复位和重新计数USB设备和USB设备。 在一个实施例中，一种用于重置和重新计数USB设备的方法包括在USB设备处检测来自主机设备的USB复位命令，响应于USB复位命令的检测来设置USB设备中的复位标志，确定是否 USB设备响应于复位标志处于损坏状态，并且导致发出单端零（SE0）信号以将USB设备重置为损坏状态，并将USB设备重新计数回主机设备，如果USB 设备被确定为处于损坏状态。 还描述了其它实施例。
