I've tried every trick I know of regarding USB Mouse/Keyboard not working.
Removed AppleHPET.kext from Extensions
USBBusFix=Yes
USBLegacyOff=Yes
EHCIhard=Yes
Tried turning "Legacy USB" support on/off in BIOS
Tried unplugging and plugging back in to same/different port
Tried USB 3.0 ports
Tried changing USB 3.0 from EHCI to XHCI (the latter prevents me even getting to the grey screen with the pointer)
Tried putting the "legacy" USB kexts directly in the S/L/E folder
Nothing works.
Given the issues many others are having who managed to actually run the installer I'm beginning to think maybe I'm better off just sticking with a perfectly running Snow Leopard system than risk a partially or completely non-functional Mavericks system. :/
And there lies the reason I never upgraded to Lion or ML. Seems like it is not worth the hassle. Until I am ready (and can afford) to build an entirely new system (new mobo/cpu/graphics/etc) I guess I will be stuck with my very stable SL system.
