各位好，
将USB2接口配置为Host模式后，可正常枚举、识别键盘、鼠标设备；
但添加了USB-storage驱动，并且在是鞥你了SCSI协议支持后，还是无法识别U盘；
无法枚举的日志打印输出为：
usb usb1-port1:Cannot enable.Maybe the USB cable is bad?
usb usb1-port1:Cannot enable.Maybe the USB cable is bad?
usb usb1-port1:attempt power cycle
usb usb1-port1:Cannot enable.Maybe the USB cable is bad?
usb usb1-port1:Cannot enable.Maybe the USB cable is bad?
usb usb1-port1:unable to enumerate USB device
