USB Fixes Over Current El Capitan

[spang1974]

All,

Getting USB over current notifications every 5 seconds when booting into El Capitan, this occurred when I tried out the Beta Versions. I don't get the notifications in Yosemite 10.10.5 so I can only assume this is being caused by the change made to how El Capitan handles USB?

Anybody else having this problem? And will it go away if I apply the USB fixes for El Capitan? Any comments appreciated. I am booting using Clover r3270 and have not installed El Capitan to my main system drive.

Solved - Basically I was using PCI USB 2.0 Expansion cards. After removing one or both I fixed the USB Devices Disabled errors. I just went back to using a external USB 2.0 powered hub. I got a lot of peripherals.

USB 3.0 fixed as well. I edited IOUSBHostFamily.kext as detailed here:

I'm in similar situation, on Yosemite it was fine, after updating to El Cpaitan getting this error, I don't have any USB extension device (internal or external), just USB keyboard, mouse and wifi, already tried removing them one by one, no luck.

Thinking about replacing USB kexts from Yosemite, what you say?
