Hi, I just built a new PC with the Z87 Stinger MB. Everything works great except that my front panel USB 3.0 ports are not recognizing devices I plug in. The devices are getting power from the ports, but get no recognition in Windows 7 when they're plugged in. The rear USB 3.0 ports work fine. The USB 3.0 Hdr ports are enabled (and hence apparently recognized) in the BIOS, which has been updated to the latest version, and there's nothing amiss in Device Manager to my knowledge.
 
Can anyone help me with this issue? I've scoured the internet for similar issues but nothing seems on point.

Thanks for the reply, NordicJedi. The motherboard is up to date as I downloaded and installed all the latest drivers and BIOS. As to the BIOS, I only disabled the onboard graphics as I have a graphics card installed. The rest of the settings are default.
 
The Stinger didn't come with the additional USB brackets -- at least mine didn't -- so I can't do the test you recommend. I was going to buy a USB 3.0 adapter from Amazon to perform just such a test, but I haven't done that yet.
 
I realize this could be either a software or hardware issue, and I was posting here in order to solicit any insight into whether there's something in the BIOS or the MB drivers that might be causing this. Just perusing this forum, I could find no evidence of a problem, so it isn't something common. Also, I've read a lot of customer reviews of my case and there isn't anything symptomatic there either. The MB and case are mITX and the cabling is very tight. One case I read about online was ultimately solved by unplugging and replugging the MB connection, so there's that. Due to the congested nature of the case I can't perform that without dismantling the computer substantially so I wanted to eliminate software issues before I proceed to the hardware tests. As I wrote above, the USB devices plugged into the front ports are getting power, so I thought that was some evidence that the connections were good. But maybe not, you just never know until you can fully test it.

Dear majorstar,
DO You getting strange beeps whille booting through 9C or 9D Post Code before you finally hear
the propper full post beep? I am getting a feelling tha we are a hardware issue. I never RMA.

Dear majorstar,
Stinger has no on- board beep speaker?
I guess You getting a completelly silent boot maybe because you selected so within
bios settings. there is a quite boot option. Try disabling this feature and investigate,
 My Z87 Classi had many issues, out of the box,  Bios 1.05 was completelly crappy,
i finnally manage to sort many issues with 1.09 Version. I use to be an Evga Fanatic, until now, [sorry EVGA, NEVER AGAIN],
i' ve built 4 EVGA PC's, Various platforms, from nvidia chipset, to x58 hosting the 6 core Extreme INTEL CPU, meanning
no cheap builts, until now the Z87 built,
 this is the forth classi running allways 4SLI , belive me there was not a single board  to
run with no Bios issues, i guess, is an Evga Tradition to make,all us, Evga motherboard owners frustrated,
and many times ungry about our mobo selection for our builts. It is obvious even within forum, having us
begging, yes begging, for a desent Bios for our valuable hardware.
It is high time that EVGA pays some attention to final users.
 

I had simmilar issue with my Stinger. I've tried many things and what helped me... was reinstalling Win 8.1. Since then everything worked well ;)
