    DH77EB Front panel USB 3 problems.

    Pradip Shah

      I have a strange kind of problem.

       

      The onboard USB 3 ports on my Intel motherboard - DH77EB with i3-3220T processor - function just fine. The problem arises when I connect front panel header to add 2 more accessible USB 3 ports to my system. These don't work but even the previously working ports stop functioning. The icon in front "Intel(R) USB 3.0 eXtensible Host Controller" turns yellow with an exclamation mark on it. Widows message is that the device cannot start. Soon as I unplug the device and reboot everything goes back to normal.

       

      BTW I am working with Win 7 x64 with all the latest updates installed. Another thing I would like to point out that when I tried installing this version of Win 7 x64 SP1 from a Zalman VE-300 external drive configured as a "USB 3.0 connected optical drive" windows threw up  an error message that it did not support the source. I ot to this point of installation thgrough bios. When I reverted to the USB 2,0 port and micro usb 2.0 on the Zalman VE-300 external drive installation was fast and went through without a hitch.

       

      Thank you.
