I have a new DZ77GA-70K board that fails to boot when a USB device (Space Navigator 3D trackball) is plugged in. The system powers up and ramps up the fan speed. The BIOS splash screen displays for a few seconds and then the power shuts off, flashing the CPU HOT LED briefly as it goes. The cycle starts over and repeats until I unplug the 3D trackball. Without the trackball plugged in, the system boots normally into windows or linux, and after the OS boot starts, I can plug the trackball in with no problem. The problem occurs on cold or warm boots and on any USB port -- rear, front-panel, USB 3.0, high-current or standard ports. I have not tried connecting the trackball through an externally powered USB hub, but that's the next step. I have not been able to find a spec for the trackball power requirements. The secondary mobo power connector is hooked up and has the correct voltages on it.
Hardware details:
DZ77GA-70K with i7-3770S @ 3.1GHz
16GB installed RAM (GSKIL F3-1600C9D-16GXM R)
power supply: Antec BP550 Plus (550W)
Video card: PNY NVidia Quadro 2000D
disks: 2x WD3200AUDX
Logitech USB keyboard & mouse
BIOS: problem is identical with 0021 and 0053 releases
Any help would be appreciated.
Thanks
