USB Noise

Anyone have any workarounds for the noise introduced when plugging USB into a PC interface?
Perhaps an adapter you recommend?

I’m having the same issue with my desktop (which uses a grounded power supply… of course), and not with my laptop using a ungrounded power supply.
I’m not sure that ungrounded USB cable exists, but it could cut this noise !

I don’t use it myself in any situation, but there are USB ground loop isolators like this that may help.
Perhaps other users have more input on this.
I guess there’s also the iDefender or something like that
