I was getting lockups when attaching my iPhone or ipad to the USB ports when I had the High power mode and on/of charge enabled on my GA-X58A-UD5. These lockups would leave no entries in Win 7 Pro 64 bit event logs and would require power cycle to reboot the PC.

I have uninstalled the on/off charge and the problem seems to to have gone away.

Is this a known issue with this board?

Which version of this driver should I install?

The product page shows the latest version as B11.0110.1 at
GIGABYTE - Motherboard - Socket 1366 - GA-X58A-UD5 (rev. 2.0)

Whereas the latest version is B12.1025.01 on this page
GIGABYTE - Support & Downloads - Utility - Motherboard

Thanks.
