Yes, this is my last hope, I've read it recently in some other theme, if I remember correctly, it was NFB15.1 theme, that changing to other USB cable solved some similiar synchro problems of someone. I will for sure test it, and will let here know. If the problem would be ONLY the cable, I will be very very happy man.
But I don't think, when it doesn't happen with Coax, it is a proof, that it would not happen with USB transfer too. I have feeling, that coaxial transmition is based on other data flow, then this asynchronous USB transfer, but maybe I mistake.
I wonder if there is potentially some sort of conflict or issue with having the USB receiver chip being powered internally by the power supply of the 11.32, and also having the computer's USB port sending power to the receiver chip as well?
