I tried it without any other usb devices plugged. And i also tried it in 
both the 3 ports available and the behavior is the same i described 
before. However the error not always happens and i was not able yet to 
find when does it happen. So i do not know how to make the error happen 
again. My first idea was that the error was not the main question 
because it was not happening all the time. I thought that the fact that 
the szap always outputting that the frontend is locked even if it does 
not have a satellite cable plugged was the main question. And i am never 
able to get any data from any filter.
For a moment it occurred me that maybe the board was damaged but then i 
tried it in standalone and it worked without problems so, i guess that, 
if there is a hw problem in the board it must be in usb. But also usb 
works when the board is detected.

Hope you can help me.
Tks for the answer,
