      T113i USB0 host 模式,连接有方 的4G模块,发AT指令信息,没有反应。lsusb 显示有2949:7383。
      1.在option.c里面已经添加了usb id,在/dev/下已经看到了:ttyUSB1,ttyUSB2,ttyUS,3,ttyUSB4,
      分别往ttyUSB1-4 发ATI指令,查询版本,均没有反应。
      4G模块是没有问题的,单独供电,而且通过fpc连接,把4G模块连接到别的平台,可以正常工作。
      2.设备树:
      &usbc0 {
      device_type = "usbc0";
      usb_port_type = <0x1>;
      usb_detect_type = <0x1>;
      usb_detect_mode = <0x0>;
      usb_id_gpio = <&pio PB 11 GPIO_ACTIVE_HIGH>;
      enable-active-high;
      usb_det_vbus_gpio = <&pio PB 12 GPIO_ACTIVE_HIGH>;
      usb_wakeup_suspend = <0>;
      usb_serial_unique = <0>;
      usb_serial_number = "20080411";
      rndis_wceis = <1>;
      status = "okay";
      };
      哪里还有问题吗?
