When the iPad released, many new owners who were used to how their iPhones or iPod Touches worked when plugged into a computer's USB port were surprised that the Apple tablet wouldn't charge if it was still in use.
Apple's knowledge base article clarifies that the iPad might not charge while plugged into a USB port because it's not able to supply enough juice to charge the battery and to power the iPad in operation. The exception to that is new Macs that can turn its ports into high-powered ones when in need and now certain Gigabyte motherboards with a new driver.
Gigabyte was proud to announce (and show off in the video below) that its full range of Intel chipset-based X58, P55, H55, H57 as well as current and upcoming AMD 800 chipset series motherboards all allow charging of the iPad both while the device is in use and not in use.
The motherboard company detailed in its press release:
Recent industry and news reports indicate that USB ports on most Windows PCs are unable to provide enough power to charge the new iPad while the device is in operation due to differences between motherboard USB power output and the device’s charging specifications. However, Gigabyte’s unique USB power design is able to deliver extra power for devices that require more than the 500mA delivered from a traditional USB port. With a simple On/Off Charge driver update which can be found on the Gigabyte website, Gigabyte motherboard users are able to take full advantage of USB charging of their iPad, giving them more options and convenience when recharging their new device.
