Hi3531D,偶发 device descriptor read/64, error -62，请问各位有遇到这样的问题吗？
启动时的打印信息如下：
usb 4-1: device descriptor read/64, error -62
usb 4-1: new full-speed USB device number 4 using ohci-platform
usb 4-1: device not accepting address 4, error -62
usb 4-1: new full-speed USB device number 5 using ohci-platform
usb 4-1: device not accepting address 5, error -62
usb usb4-port1: unable to enumerate USB device

跟到最底层的代码处：
usb_get_descriptor 调用
usb_control_msg(dev, usb_rcvctrlpipe(dev, 0),
                                USB_REQ_GET_DESCRIPTOR, USB_DIR_IN,
                                (type << 8) + index, 0, buf, size,
                                USB_CTRL_GET_TIMEOUT);
