if it was on the signal line, i would have constant disconnects. those are pretty audible pops on my interface, not just a few microseconds spike. so it has to be ground. Can't isolate that

and i need more current than 200mA too.
But it's solved now, that one hub only has the mouse and keyboard and a couple of usb charging cables
Still need to disable wireless charging when recording though, that thing is an EMI nightmare
