忘记说了, 作为device模式时, 很正常, adb通信很好.

@whycan 在 T113 USB0不能读取U盘 中说：

find / -name usb_host | xargs cat

一样的

alias usbhost="cat /sys/devices/platform/soc@3000000/soc@3000000:usbc0@0/usb_host"
alias usbdevice="cat /sys/devices/platform/soc@3000000/soc@3000000:usbc0@0/usb_device"

T113 usb1读取U盘正常, usb0不能读取.
表现为, 插入U盘毫无反应, 就和没插入一样.

确认已经进行过usbhost指令切换.

使用usb1时, 输出:

进行 usbhost 切换时, 显示为:

进行usbdevice切换时, 显示为:

配置如下:

/*

上边注释掉的 reg_usb0_vbus 配置是抄的 reg_usb1_vbus, 以为是这里配置错了呢.

	reg_usb0_vbus: usb0-vbus {
		compatible = "regulator-fixed";
		regulator-name = "usb0-vbus";
		regulator-min-microvolt = <5000000>;
		regulator-max-microvolt = <5000000>;
		regulator-enable-ramp-delay = <1000>;
		gpio = <&pio PB 3 GPIO_ACTIVE_HIGH>;
		enable-active-high;
	};

	reg_usb1_vbus: usb1-vbus {
		compatible = "regulator-fixed";
		regulator-name = "usb1-vbus";
		regulator-min-microvolt = <5000000>;
		regulator-max-microvolt = <5000000>;
		regulator-enable-ramp-delay = <1000>;
		gpio = <&pio PB 3 GPIO_ACTIVE_HIGH>;
		enable-active-high;
	};

经过测试也不行.

把usb0 的 usb_port_type 配置为 1 时, 内核启动可以看到如下输出:

插入U盘也毫无反应.

求教到底是哪里的问题.
