控制USB设备控制器连接主机,connect-连接,disconnect-断开连接 /sys/devices/platform/usb0/fe800000.dwc3/udc/fe800000.dwc3/soft_connect 查看当前USB设备控制器的状态 /sys/devices/platform/usb0/fe800000.dwc3/udc/fe800000.dwc3/state USB设备控制器的状态定义如下: "not attached","attached","powered","...
Function驱动和UDC驱动绑定的时候,实质上是通过usb_udc_connect_control函数控制设备和主机连接和断开。主机通过vbus向设备供电,若设备不需要主机供电,则udc->vbus=true。若需要,则通过usb_udc_vbus_handler函数更新vbus的状态,像U盘、移动硬盘这类设备,必须要主机供电,供电以后才能开始工作和被主机枚举。 [include/linu...
通过属性文件可以控制udc如: softconnect static ssize_t usb_udc_softconn_store(struct device *dev, struct device_attribute *attr, const char *buf, size_t n) { struct usb_udc *udc = container_of(dev, struct usb_udc, dev); if (sysfs_streq(buf, "connect")) { if (udc_is_newstyle(udc...
