I just fixed it. Sorry. It seems that was something from my motherboard. I connected it to USB 3.0 and everything was ok, but it was just not working. Then i plugged it to USB 2.0 and everything seems perfect again. Thanks anyway for your time!
It was working perfect, but i reinstalled my windows and all the setting and drivers got reseted, so I probably missed something or did something wrong when i tryed to set it up again.The ux2 it's definetly not broken. 100%
