Rear USB3.0 stopped working (no reason)

[Dnk_Productions]

The rear USB3.0 ports stopped working for apparently no reason. I updated to 10.8.3 and everything was working fine and then one day it just stopped. Any idea what could have happened. I tried setting bios to optimized defaults. THe drive is getting power but not mounting. The front USB3.0 ports ARE WORKING CORRECTLY.

This is very annoying. I have attached the USB device tree as well as extensions with "USB" in the title

I am having the same issue with my

GA-B75M-D3P. Shows up in system profiler, but noting works.

Were you able to fix yours? ​

over clocking can kill usbs if you have done this need to clear the cmos unplug power cord wait 5 secs put jumper on pins 12 wait 15 secs put back on pins 23 plug in power cord reboot redo bios settings.

Thanks, resetting the cmos worked for me. Before you do so go ahead and save current bios as a profile. Once you reset you can go into the bios and simply load the profile. You're back up and running in minutes.

Thanks again Stehor
