This functionality depends on setting the USB over-current register to disable at bootloader phase, for example U-Boot: https://patchwork.ozlabs.org/project/uboot/patch/20241012031328.4268-6-minda.chen@starfivetech.com/ If the over-current register is not prepared for us then the result is no change in functional outcome with this patch applied; there is an error visible to the user and this additional usb configuration fails (same as it is now). On Milk-V Mars with four USB-A ports this applies to one of the USB-A ports and the remaining three VL805-connected USB-A ports via PCIe are not changed.
