Midi stop working after some time

[Renzo777]

Hi Guys, im recently buy a Hackintosh here in Argentina, i work in audio and i used the midi inputs for almost everything.
Im having this problem that is getting me crazy, when I start te computer i can record midi, for something like 5 or 10 minutes, then it automatically stops working, the crazy thing is that the midi light of my Foscurite Scarlett 2i4 is ON , like telling me that is recieving midi, but when i play nothing happens.
Also i used the Microkey via USB but the same things happens, stop working randomly.
This thing happens in all my DAWS (Reaper,Logic and Pro Tools) so there must be some hardware problem, the unique form to use midi is restarting the computer or closing and opening the session user, and then i have midi again..for a randomly time.

My build is:

Thanks Bob! Couldn´t fix it, i dont know if my problem is in the usb ports, because my Hackintosh recognize my Focusrite Scarrlet 2i4 and all its features, the only problem is that midi stop working after 10/15 minutes, i connected my Microkey via USB 2.0 and USB 3.0 and the problem is the same.
Also when i connect my korg sp 170 to the MIDI ports of the Focusrite scarlett, the problem is still the same, so i dont know what could be!!
