As per USB 2.0 specification 7.1.5.1: The voltage source on the pull-up resistor must be derived from or controlled by the power supplied on the USB cable such that when VBUS is removed, the pull-up resistor does not supply current on the data line to which it is attached.

RaspberryPi Pico USB Device Controller.
|
|
|
|
Example of enabling the controller with vbus detection:
|
|
|
|
&pinctrl {
|
|
usb_default: usb_default {
|
|
group1 {
|
|
pinmux = <USB_VBUS_DET_P1>;
|
|
input-enable;
|
|
};
|
|
};
|
|
};
|
|
|
|
zephyr_udc0: &usbd {
|
|
status = "okay";
|
|
pinctrl-0 = <&usb_default>;
|
|
pinctrl-names = "default";
|
|
};
|
|
|
