The JUSB1 connector [on your motherboard] supports MSI’s new SuperCharger technology which provides quicker USB charging of your cellular phone or other USB-powered devices. To enable this feature, please install the MSI SuperCharger application on your computer. When the SuperCharger application is turned on, the JUSB1 connector will convert data channels to extra power channels to quickly charge your connected device.
Please note that when the SuperCharger application is turned on, data transmission and synchronization over the JUSB1 connector will not function. To enable the JUSB1 connector to function as a normal USB 2.0 connector, please turn off the SuperCharger application. When the computer is in stand-by or hibernation mode (S3/ S4/ S5) Super- Charger mode will automatically be enabled.
