I have done different tests to see what results I get ... and nothing in the last one I managed to make images of (and without much success, too).
In the attached pdf, you will see a table where I have tried to describe what tests I have done.
In the compressed file are the sv305_pro_dump_vN files of each test (where N is the test number or version, which I named). My dmesg results is like 1-1.3 (connected directly to USB3 port) or 1-1.4.1 (from Hub powered usb3). On "cat " instructions I put "1u" , this is correct, don't you?
I hope it helps you with something ... If I have to clarify something, tell me. Or if some other test needs to be done, too.
I have a raspi4 with 4Gb of ram, astroberry 2.0.3 and I have either connected via VNC (via web) or remotely via PC (Ekos).
Thanks for everything.
I will waiting your news
