i have added a USB3.0 PCIe card (Inateck KTU3FR-4P USB 3.0 expresskarte 4 port) to my Mac (MacPro Early 2008, OS X 10.8.4 (12E55))
...with this all is working as it should, no problems with shutdown.
To have better access to the USB3 ports i have now bought an USB3 Hub (Inateck HBU3VL2-4 4 port USB 3.0 Hub without extra current needed).
And this is what makes me problems. If i connect the Hub to the Card, and afterwards shutdown my Mac, it restarts itself after 1 second.
The console log shows some strange info about current and an error (SetFeature(kUSBFeatureDeviceRemoteWakeup) failed. Error 0xe000404f) ...
But the Systeminfo shows well...
And during working with the mac all is OK. Also if i connect a hdd to the hub, it is working as it should...only shutdown doesn't work if the hub (with or without any device on it) is connected to the card.
Shutdown/restart Log:
There is no wake reason...
Any ideas how to fix this are welcome?
Thanks, richard.
