Mouse freezing on motherboard USB ports

[AbstractNotion]

I built a computer this past week. I am using a Logitech K270 and Performance Mouse MX with one unifying receiver. My problem is that whenever I plug the receiver into a USB port on the back of my motherboard the mouse cursor becomes jittery. Sometimes it will stop while I am using it, and then I need to lift the mouse to make it move again. However, if I plug the receiver into one of the USB ports on my case the mouse works perfectly. Do you have any suggestions about how to make the mouse work on the rear USB ports? Thanks.

Good batteries in the mouse and keyboard? Setpoint will tell you if they need replacing, if you have installed it. I have a M570 wireless Trackball that uses the Unifying receiver. My receiver is plugged into the motherboard USB port on the back of my tower, no problems. Any other wireless devices that may be interfering with the signal?
