sorry to bring this back from the grave :P

But i have the same problem - A8N32 SLI - Deluxe/7800GTX Though/10.5.2 Rev.2

I tried kalaway before but buggy this seems much more stable

My resolution etc is fine but the only problem is that my usb devices do not work, iphone is not being picked along with anything else apart from my keyboard and mouse.

Tried the kext but nothing, tried bios change nothing, the only thing is something about booting with -v which i havent tried... if it could be that, can someone explain unless there is another fix

thanks,
chris
