"USB Devices Disabled" - USB problem?

Hi, i have strange problem. System constantly displays me a message:

when I close it immediately pops up next. I know it comes from the apple keyboard [a1243], but keyboard works fine, I can write on it. I might add that on Yosemite does not have this problem. Any ideas?

mb: z87x-ud3h with fresh install 10.11.1

If I recall that's a problem with the Renesas USB on that board. Try disabling the Renesas USB in BIOS and plugging devices only into the chipset USB ports, and see if that fixes the problem.

I don't have this option in BIOS settings.

OK, then I guess just make sure you're not plugging anything into the Renesas ports vs. the chipset ports.

I heve 6 USB ports on ma MB and on each of them I gets this message. I might add that the on my MacbBook Pro (mid 2010) i have the same problem. This is strange, before the update everything worked properly ;(

Make sure you read the entire text. Carefully. More than once.

Then pay special attention to the "Specific Recommendation" section that pertains to your hardware.

Ok. I just installed FakePCIID.kext and FakePCIID_XHCIMux.kext wia Kext Wizard and look like it's working. I do speediest later.

Now gets interesting:
When i switch option to Mirror, system stops displays me a message "USB Devices Disabled". When i switch back to Use as separate display immediately shows up message.



This is odd. I do not know what to think about it.
