Vu+ Zero and USB Turbo dvb-t or rtl2832 zapping problem

[Mart336]

Got a problem when changing DVB-S to DVB-T...box is freezing (not completely but unable to use). Only way to use it again is power off/on or terminal restart box over telnet.
This problem is not new but still not solved. I find some posts about usb turbo tuner zapping with open*** images but no solution for this problem. Almost every post what i found say's its vu turbo tuner driver problem but it's not because when i used my older rtl2832 theres no difference. About 2016 august this problem is not active but in november it's back.

Also added picture how it looks, not complete freeze but remote not working...
If anybody knows how to solve it then please share information.

WIN-WIN

Seems like Cccam caused this problem.
If anybody got simillar problem try to disable cccam and use oscam (NB! after cccam is disabled restart tuner).
