Hi all, I just recently built my computer and I can't seem to figure out why my USB 3.0 ports won't work on my motherboard. It is a ASUS z87-a (running Win 7 64bit), I downloaded and installed the latest USB 3.0 drivers from ASUS website, my bios says the ports are all enabled, my device manager says they are all updated... So why is it not working!?!?!

Please help!

Oh and another thing, every time I start my computer it wants to run this file "iusb3mon.exe" It keeps showing up every start up. Not sure why...

iusbmon.exe - USB 3.0 eXtensible Host Controller Monitor is a process from Intel that runs on start-up (as USB3MON) and remains running that manages various USB 3 connections if your PC is connected to a USB 3.0 powered device. It's a monitoring program for power consumption by your connected usb 3.0 hardware.

Are you sure the usb plug on the motherboard is fully connected? Only asking because mine doesn't stay securely connected if/when I move wires around inside my case.

Nevermind, I fixed both of my problems.

The iusb3mon.exe that shows up on every start up is because the .zip file I downloaded from the ASUS website was "blocked." So I unblocked it, extracted, and reinstalled. Now it doesn't show up anymore (restarted 3 times to confirm).

Next I just updated the mobo bios to the latest and seemed to have fixed the usb 3 port issues.

Thanks anyways for replying though.
