New member here, interesting reading 2 say the least.
I've got a new rig, and I am getting this infuriating usb connect/disconnect problem as well.
I have the h150pro, corsair rgb ram, 7 ll120 rgb fans, commander pro and lighting node with icue installed.
About 75% of the time icue starts and does not show my pump or lighting node. 100% of the time I get the usb connect/disconnect problem.
If I uninstall icue, then reinstall it shows everything but the usb problem still happens.
It also seems to happen when using external usb devices as well.
Glad I found this thread, I was going to start ordering new parts.
I will set everything to a static colour and see how it goes.
What a bad situation this is!!!
