I can only speak to what worked here. I used to constantly lose connection
to N1MM and also to my Winkeyer (and later, my YCCC SO2R+ box).all on
separate USB cables.
Occasionally, even at QRP levels.
I was plagued with it. My shack looked like a stockpile of Ferrite had
gobbled up all my cables.
In the end, the one thing that proved most valuable was actually super
simple. I took a teeny tiny wire...perhaps a #26, stripped a couple inches
of insulation off the end of it and wrapped it around the shell/shield of
one of the USB cables entering my (plasticky) 10yr old laptop. I attached
that wee pigtail of wire to my station ground with a larger wire.
Voila! 99.9% of my RFI instantly went bye bye.
Good luck.
