SGPro keeps dropping connection to Heq5 in Eqmod

Hello All,
As I am very new to SGPro I need help with getting my gear working.
Does anybody know of problems with USB 3 hardware as I seem to be getting all kinds of random malfunctions.
The only way I can get any communication to my mount going, is to connect my eqdir to a USB 2 socket but this also keeps dropping out at irregular intervals and hence is unusable.
I am using an up to date Windows 10 machine with plenty of power in my observatory .
Any help to get some of my issues sorted would be most grateful.
Many Thanks in advance
