USB Problems on nMP

[armut]

Hello,

I have a problem with my USB ports on my nMP.
If I connect more than two or three USB devices (external HDd) to my nMP my Logitech USB mouse is stuttering. Symptomps are like empty battery but batteries are full.
So what can be the reason for this?

USB 3.0 drives give off RF interference around the cable connectors and your Logitech dongle is probably right next to that. You could get a USB extension cable and put the Logitech dongle on the end of that, away from the USB 3.0 drive cables.
