忘记说了, 作为device模式时, 很正常, adb通信很好.

Reply: T113 USB0不能读取U盘
@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 USB0不能读取U盘
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.
