USB 3.1 random disconnects

[llamafilm]

My motherboard has one USB 3.1 port in addition to several USB 3.0 ports.  When I connect a hard drive to the 3.1 port, it works sometimes, but randomly ejects.  I see the following messages in system.log repeating as long as a device is connected.

Edit: Those log messages were because the USB 3 stick I was using to test happened to by a [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] installer.  I guess I can ignore that, although I'm curious why that URL is mentioned.  But the problem remains — random disconnects when using other drives on this port.

I understand tony's stuff is frowned upon here, but I'm not sure what you mean exactly.  Perhaps it would be better to just delete this thread and start a new one when I have more troubleshooting details.  Unfortunately I don't have privileges to delete my own thread.
