my board is remote atm and does not have the usb peripheral cable hooked in.
However, I did load g_zero and looks like 73 is registered.

Looking at arch/arm/boot/dts/am57xx-beagle-x15.dts
looks like extcon is used for both host and peripheral - am I mistaken - if I am right,
then at least the host devices seem to work (usb storage).
extcon_usb1: extcon_usb1 {
compatible = "linux,extcon-usb-gpio";
id-gpio = <&gpio7 25 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&extcon_usb1_pins>;
};
extcon_usb2: extcon_usb2 {
compatible = "linux,extcon-usb-gpio";
id-gpio = <&gpio7 24 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&extcon_usb2_pins>;
};
...
&usb2_phy1 {
phy-supply = <&ldousb_reg>;
};
&usb1 {
dr_mode = "host";
pinctrl-names = "default";
pinctrl-0 = <&usb1_pins>;
};
&omap_dwc3_1 {
extcon = <&extcon_usb1>;
};
&omap_dwc3_2 {
extcon = <&extcon_usb2>;
};
&usb2 {
dr_mode = "peripheral";
};
Anything I am missing?
