Some newer Gigabyte motherboards can supply increased power to a USB port. This feature is enabled via a driver.
“The 3x USB Power Boost from GIGABYTE is designed to deliver the utmost compatibility and stability for USB devices, such as external storage devices or optical drives, by supplying sufficient power through a single USB port.”
“3x USB power from USB 2.0 ports is available with certain models only.”
