I understand that you are having problems with the USB 3.0 ports on your motherboard.
In regards to your inquires, the problem that you are experiencing does not seem related to the other problems reported for the BIOS version 0049.
I recommend you to test with a different USB 3.0 front panel to check if this is directly related to a compatibility problem or a problem with your motherboard.
I can offer the following more detailed information on my problem with Front Panel USB 3.0 connectors on my Antec Solo II case not working with Intel DZ77GA-70K motherboard:
1. Both USB 3.0 ports on the Intel-supplied front panel adapter housing works fine when plugged in to either USB 3.0 motherboard headers, labeled MM and NN on Page 15 of your Board Layout documentation (G54936-002).
2. When plugging in the Antec Front Panel USB 3.0 connector to the header labeled NN (closest to the rear of the case), neither USB port works (ie nothing is recognized in Windows 7).
3. When plugging in the Antec Front Panel USB 3.0 connector to the header labeled MM (closest to the FRONT of the case), the BOTTOM USB port on the front of the Antec case WORKS, but the TOP port does not.
4. The blinking Power LED seems to be unrelated to the USB problems. I had a blinked Power LED tonight and nothing was plugged into either USB 3.0 motherboard header. When this occurred, the BIOS 0049 setting for General Optimization was UN-CHECKED but the Graphic Optimization was CHECKED. All boot devices like USB, Optical, and LAN were UN-CHECKED.
Exactly what is the blinking Power LED indicating to us? (FYI it is blinking right now and I don't know when is started or why)
Thanks for any assistance as we try to get to the bottom of this issue.
Bob, I was able to reproduce this problem as well. On my Antec Solo II case, all USB 2.0 and 3.0 ports on the back are working. However, on the front of the case, the top USB 3.0 port does not recognize a flash drive or any other device. The bottom USB 3.0 port on the front works, and both USB 2.0 ports work.
So, in summary...
Back of case: 4 of 4 USB 3.0 ports work.
Back of case: 2 of 2 USB 2.0 ports work.
Back of case: 2 of 2 USB high-current ports are untested.
Front of case: 1 of 2 USB 3.0 ports work (top port fails, bottom port works)
Front of case: 2 of 2 USB 2.0 ports work.
I tried to swap out the USB 3.0 cable to the alternate header on the motherboard, but the problem remains. The top USB 3.0 port on the front of the case still does not work.
Were you able to receive a response from Antec to help in determining if this is an Intel motherboard issue or an Antec case issue?
Thank you and good luck!
Thanks kindly, Bob. I will look forward to your review of what transpires after your replacement arrives.
If the problem turns out to be an Antec hardware problem related to one of USB 3.0 ports on the front of the case, I will simply request a modest price adjustment on a future purchase, if they are willing. I do not intend to disassemble my entire build for one errant USB 3.0 port. In the greater scheme of things, it's a minor inconvenience.
As I suspected, the replacement front panel assembly from Antec with USB connectors and wiring did NOT fix the USB 3.0 Front Panel problems. However, when attached I now get the continuous popup message in Windows 7 of "Power Surge on USB Hub". This occurs when the USB ports are connected to the motherboard header, but even when no USB device is attached.
Thanks for the update, Bob. I am still experiencing the same problem USB 3.0 failure with the DZ77GA-70K motherboard. All USB ports work, with the exception of the top USB 3.0 port in the front. The other USB 3.0 and USB ports, front and back, all work.
Regarding the "Power Surge on USB hub" message you described, after I installed the latest drivers, disconnected all devices, rebooted, and reconnected all devices, I have not experienced that issue again for a couple of weeks now. I vigorously tested all USB 2.0 and USB 3.0 ports, and all work perfectly with no error messages, except for the top USB 3.0 port in the front, which is not recognized.
Other than this minor annoyance, I am very pleased with the board and my entire new build so far. If only the OCZ SSDs would come down in price a little, I would buy a new 512GB Vertex 4 for a second internal SSD!
Regarding the USB issue, I now wonder if it could an an ANTEC design flaw, an Intel BIOS flaw, or a driver flaw.
Has anyone else experienced an issued with one of the front USB 3.0 ports with the DZ77GA-70K?
I'll submit a trouble ticket to Intel shortly.
It looks like you, Janne, and I are experiencing the identical USB 3.0 front port problem with the same motherboard. Anyone else?
I reported to Intel, but the agent said she was unaware of the issued. I provided her with links and she thanked me for bringing the issue to Intel's attention.
USB 3 is a bit broken on the Z77 Intel motherboards. It seems to be related to pin 10. For me, my Fractal Design USB 3 port was not working, a new bios solved that issue partially. Now when i connect a USB flash drive to that port i get Power Surge messages but the drive works without problem. Anyway, i try to avoid using the Fractal port, i use Intel USB 3 bracket instead because that one works fully.
Here is some more threads about this issue:
I updated to BIOS version 0053 and plugged the Antec Solo II case front panel USB 3 connector into the motherboard header labeled MM (closest to the FRONT of the case). The BOTTOM USB 3 port on the front panel now seems to work, but the TOP USB 3 port does NOT. The Windows 7 power surge warnings no longer seem to appear since the BIOS update, and the front panel power LED no longer blinks.
