Hey guys. I'm having as strange USB issue with my Maximus VII Hero.
I picked up a Audioengine D1 DACc, all but the lower USB 3 ports (circled in image) didn't work with the DAC at all, I get a warning about a hardware malfunction.
I had a friend bring over a Hitachi Touro USB 3 hard drive, it wouldn't work in anything but the lower 2 USB 3.0 ports as well.
Yet my Keyboard and mouse are connected to the black USB 2 ports work fine (DAC wouldn't work in them either), USB 3 flash drives, printer, USB 2.0 2.5" hard drive, MS Xbox360 wireless receiver, mobile phone all work perfectly in every port. I also have a PCI slot USB 2 panel connected to the internal USB 2 ports and everything works perfectly in them too.
If I plug in a USB 3 hub into the middle USB 3 and top USB 2 ports the DAC works perfectly through the hub....
Is there something wrong with my motherboards or do the bottom 2 ports supply more power than the others?
You can close the thread, no one knows, returned the board and got a Gigabyte Z97X Gaming G1 Black Edition instead. ALL USB PORTS WORK PERFECTLY WITH THE DAC, and strangely enough my front panel that wouldn't work with the Hero AT ALL.
