After a few months of working fine, my mouse and keyboard are cutting in and out. High Sierra on X58 build.

I know on the older X58 I have to disable USB3, but I've never had a problem with the keyboard suddenly stopping. The mouse started first, then I switched mice, got another, similar problem. Then the keyboard.

I reboot and it works for a while then cuts out.

The High Sierra upgrade just happened about 2 months ago.

I don't run USB 3 and I the GA X58A UD3R. K120 USB wired keyboard and G500 mouse/ universal logi mouse as sub.

Any ideas why it would stop working all the sudden.
