T113 USB0不能读取U盘

[hxhlb]

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:

[ 1396.620617] android_work: did not send uevent (0 0 00000000)
[ 1396.627196] hci: ERR: sunxi_ehci is null
[ 1396.631626] hci: ERR: sunxi_ohci is null
host_chose finished!

进行usbdevice切换时, 显示为:

[ 1381.645354] hci: ERR: sunxi_ohci is null

配置如下:

/*
 *usb_port_type: usb mode. 0-device, 1-host, 2-otg.
 *usb_detect_type: usb hotplug detect mode. 0-none, 1-vbus/id detect, 2-id/dpdm detect.

&usbc0 {
	device_type = "usbc0";
	usb_port_type = <0x2>;
	usb_detect_type = <0x1>;
	usb_detect_mode = <0>;
	usb_id_gpio = <&pio PG 0 GPIO_ACTIVE_HIGH>;

	status = "okay";
};

&ohci0 {
	/*drvvbus-supply = <&reg_usb0_vbus>;*/
	status = "okay";
};

};

&ehci1 {
	status = "okay";
};

&ohci1 {
	status = "okay";
};

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.

[whycan]

@hxhlb

find / -name usb_host | xargs cat

试一试这个。

[hxhlb]

@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"

[hxhlb]

忘记说了, 作为device模式时, 很正常, adb通信很好.

大佬解决了么，我最近也在用usb0挂载U盘
