Mouse stuck at left corner on the Installer screen

[bernardoliz]

Hello people.

I know there are a lot of threads about that, but i couldn't get my issue any help with anything i've seen until now.

I'm using UniBeast method to install Mavericks. I can get easily to the Installer, with full HD and Wi-Fi, USB keyboard working perfectly: what allows me move around in the steps, until the 'select disk' part, where i need to format the HD (which i can't do without mouse). Yes, because the mouse keeps stuck in the upper left corner. Doesn't click, doesn't move.

Tried USBBusFix=Yes, USBLegacyOff=Yes, and tried using a PS/2 mouse. Nothing works. Also tried other USB Ports and etc. And i have tried with the OS X 10.6 Snow Leopard disc, either. Same problem.

Oh, and i guess this is useful::

CPU: Intel Core i7 4770K
RAM: 16GB Corsair Vengeance 1600mhz (using only one stick of 8GB)
MB: Gigabyte GA-Z87-D3HP
SSD: Samsung 840 EVO 250GB
VIDEO: NVidia GTX 760 - EVGA
PSU: Corsair RM 650

If anyone could help me, i'd be much grateful!
