Sleep mode issue

Hi Lidiani,
You solved this problem? I have the GA-Z87X-UD3H. I have the exact same problem.

Begin to investigate the problem. Removed the HD5770 and switched on Intel Graphics HD4600. The problem remains. In system.log I see following:

Jun 23 19:32:02 Romans-Mac-Pro kernel[0]: Wake reason: PXSX PEG0 PEGP PEG1 PEG2
Jun 23 19:32:07 Romans-Mac-Pro kernel[0]: RTC: PowerByCalendarDate setting ignored

Jun 23 19:32:07 Romans-Mac-Pro kernel[0]: The USB device HubDevice (Port 6 of Hub at 0x15000000) may have caused a wake by issuing a remote wakeup (1)

Does anybody have any ideas?

USB Prober app sees it:

Port 6: Status: 0x0203 Change: 0x0000 HubDevice

What's this?
