iPad charging issues

[Catbert6]

Hi All

I have been very happy with my recent GA-Z68X-UD4-B3 based build - it is now stable at 4.0 ghz and doing nearly everything I ask of it.

One thing it won't do is charge my iPad over USB while the iPad is awake (I know it is probably charging while it is asleep - see here). I have tried various cables and various ports, and while both iPads and iPhones mount, only the iPhone will charge. It is not an inherent hardware limitation as when I boot into Windows 7, the iPad is clearly charging.

I used Multibeast 3.8 and a pre-edited DSDT correct for my board and bios version from the data base. I have used the settings below. Have I missed anything?

It's a known "issue" with the iPad requiring more power from the USB port.

There are drivers for Windows 7 provided by gigabyte but I haven't yet come across anything for OS X.

The hardware in my sig charges the iPad (1 & 2) just fine with the drivers installed under windows 7 but not with any flavour of OS X (It does charge but REALLY slow).

I thought that might be the case - I checked and it does charge (as long the it is not on) but, as you say, it is really slow

from what I've read, new mac computers will allow 1100mA for charging, but the old ones only allow 500max. I've been trying to find a list of supported products in order to find out if there's a way to make the profile work. Currently mine is recognized as a Mac Pro 3,1 and only allows 500mA in Lion. in windows, the gigabyte drivers work and it will charge my ipad and iphone 4 quite fast.Im not sure what others have tried, but it seems to me that the key is in the power settings or profile. perhaps a kext is required, but I thin its just a profile issue.
