I recently introduced a humming/buzzing sound in my home studio, coming from my USB audio interface (Behringer U-Phoria UMC202HD) into my mixer. After a bit of unplugging stuff, I found out that the noise comes from attaching the internal USB-hub on my monitor to the laptop. I have another USB(-C)-hub connected to the laptop, which does not generate any noise. No matter if I connect the monitor USB hub directly to the laptop, or via the other hub, the noise appears. All my gear are connected to the same wall socket for power.
I have a lot of USB equipment, and I need more ports than my laptop and the first hub provides. Is it possible to eliminate the noise generated by attaching the monitor USB hub? Will I have the same problem if I buy another hub?
