[SOLVED] Why is there a limit to how many USB devices I can have plugged in?

[egg2]

Hello. I recently upgraded my mobo and CPU and am now having a problem where if I have three USB audio devices plugged in one of them will not show up as an option. If I unplug the one that's not working and plug it back in, it'll start working but another device will stop working.

I did some research and I think it has something to do with the number of endpoints I'm using, but I can't move my devices to a USB 2.0 because all my ports are USB 3.0. Thanks for any help!

You can use much more than three USB devices. Start with this "I recently upgraded my mobo", did you do a clean Windows setup after you did? If not, do that first. You may want to list exactly what these devices are and how you are connecting them. Using a hub or directly to a motherboard? Powered USB hub or not? Did you try using these devices on another computer to see if they work there? Without listing some details no way to find anything out.
