On Odroid U3 (Exynos4412-based) board if USB was initialized by bootloader (in U-Boot "usb start" before tftpboot), the HUB after successful probing was not visible in the system ("lsusb"). Connected devices were not visible neither. The USB3503 takes optional regulator so provide one - buck8 on Odroid U3. Additionally switch the control of buck8 to GPIO mode. It is faster than I2C/register mode and it is the easiest way to disable it (regulator state is a logical OR state of GPIO and register value).
