Enable USB_VBUS on demand iMX8M Mini

[dpog]

Is there a way to toggle the USB VBUS only on demand? My current design switches on the VBUS on Kernel-startup, but it does not turn it off when nothing is connected. The port is configured as host, the gpio1_14 corresponds to the USB2_PWR_EN-Pin. I tried to use the ID-Pin for toggling, only to have no voltage at all on the port.

reg_usb_b_vbus: regulator@2 {

        compatible = "regulator-fixed";

        regulator-name = "USB_B_VBUS";

        regulator-min-microvolt = <5000000>;

        regulator-max-microvolt = <5000000>;

        gpio = <&gpio1 14 GPIO_ACTIVE_HIGH>;

        off-on-delay = <20000>;

        enable-active-high;

    };

&usbotg2 {

    vbus-supply = <&reg_usb_b_vbus>;

    over-current-active-low;

    dr_mode = "host";

    pinctrl-names = "idle", "active";

    pinctrl-0 = <&pinctrl_usb2_idle>;

    pinctrl-1 = <&pinctrl_usb2_active>;

    status = "okay";

};

What's your design for the USB2? Could you share us the schematic of this section?

It's the same design I mentioned earlier in this post:
