mpc renaissance and apogee duet firewire trouble

Hi guys. First of all I apologize for my English, there may be mistakes in my words.
I have a problem
My setup:
- MacBook Pro 15' retina mid 2012 top model, OS X Yosemite 10.10.5
- Apogee Duet FireWire connect with Apple FW-thunderbolt adapter
- MPC Software 1.9.7
- MPC Renaissance connect with USB 2.0 hub (cuz without hub mpc not working well, i think you know about this problem)

And now my **** problem.
I can't use my mpc and apogee at the same time. After 10-20 minutes of working my OS X shutting down and restart. Or MPC lost connecting with macbook ( warning on display) and system is freezes.
I have tried reinstall software and drivers and changed settings. No result.
If i use only duet or only mpc its all good.
Please help. How can I solve my problem? Whats the problem of my mpc and duet conflict?

no, hub is passive
I wanted to buy active hub, but my mpc is working well with my old passive hub when apogee duet isn't plugged

Today I bought active hub 2.0.
While working fine
