Hi,
+ usb3_hub_5v: regulator-usb3-hub-5v {
+ compatible = "regulator-fixed";
+ regulator-name = "USB_HUB_EN";regulator-name = "vcc5v0_usb30"; "USB_HUB_EN" is the pin name.
+&usb_dwc3 {
+ dr_mode = "host";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ status = "okay";
+
+ hub_2_0: hub@1 {
+ compatible = "usb5e3,610";
+ reg = <0x1>;
+ vdd-supply = <&usb3_hub_5v>;This is incorrect... The hub is powered by VCC_5V0. VCC5V0_USB30 provides USB VBUS. Thanks, Chukun
