The hub's power and reset come from the "usb2109,2817" and "usb2109,817" nodes in the device tree, which need the onboard_usb_dev driver. Without it, the hub regulator (USB30_HUB) stays off and the board's four USB-A ports are dead. Enable USB_ONBOARD_DEV as a module, as arm64 defconfig does. Tested on a Banana Pi BPI-F3 with v7.4-rc1 (dwc3 enabled as a module): the module autoloads, the hub comes up on both buses and a USB mouse on a USB-A port works. Without it, only the root hubs are seen. This patch was prepared with the help of an AI assistant (Claude), which also ran the build and boot tests.
