I have rgb enabled razer keyboard, mouse, mat and speakers all connected to the usb ports on the back of my motherboard. The 5th item is my base station but it doesn't connect at all when i connect it to a rear usb port (of which 2 are spare) it only works when on the front usb port which is a nuisance for cable management.

The ports do work as I can put in a usb stick or swap things about just fine.

What's going on?
