Hi all,
I have a Behringer UMC202HD USB Audio Interface and a Pioneer DDJ 400 DJ Controller(With built in audio interface)
With either the DDJ or the UMC plugged in I get no annoying "USB Noise" but plug them both in and its there.
Anyone know how I may go about resolving this ?

Haven't tried it myself, but these are supposed to help: Behringer MicroHD HD400 Ultra-Compact 2 ... Destroyer

Have tried both, plugged into a hub and direct to rear ports on motherboard and various combos thereof, same issue.

Update:
The noise is now gone with the DDJ on the powered USB hub and the UMC on a motherboard USB connector.
I do not know why this solves the problem, will have to look deeper some other time for for now.. no noise, yay.

Probably ground loops: alternative electrical paths through the shield / ground
Glad you fixed it!

Like Bert said, probably a ground loop. Great that it's fixed

Have you tried a ground loop isolator?

Do either or both of the devices use USB cables with a ferrite choke?
