I have the same mobo and had also some troubles. I had the same troubles with an Asus mobo.
I did not disable USB and acpi in the bios but I installed without acpi.
You can select this in the selection screen when you install.
If you disable USB in the bios, in my opinion this is like a switch so Suse never can find it since there are no bios functions, no irq or what so ever.
