On my old AsRock board, which had a front USB 3 connector (AsRock X58 Extreme6), I was able to use my iPad via connecting to the front panel USB 3.0 port (which connector to the front USB 3.0 connector on the MoBo), and the USB 3.0 ports actually powered the iPad. However, on my new Asus P8Z77-V Deluxe MoBo, I am using the same front USB 3.0 connector that I used with the AsRock, and I am plugged into the Asus USB 3.0 front port connection on the MoBo, but when I plug my iPad into the USB 3.0 port (either one), I get an error message that a power surge occurred on the USB hub, and I should disconnect the device and reset the USB port.
Am I not able to plug the iPad into the USB 3.0 ports when the connector is plugged into the Asus MoBo? Is the Asus connector not powered like the AsRock? Really seems odd for a more advanced board to seemingly provide less functionality in this respect. Or do I just need a new USB 3.0 front header (and, if so, model number, please)?
