hobelware Posted November 15, 2015 Share Posted November 15, 2015 I got the exact same behavior with a Belkin USB 2.0 / FW 400 PCI Card (F5U508-V Rev 1.2) .. the controller's chips are VIA VT6306 for Firewire, (which works flawlessly) and VT6214L for USB 2.0, which is recognized as USB Host Controller, but got somehow screwed up on its USB Hub Power status. I get the notification mentioned above anytime. No difference wether I got something plugged in or not and plugged in devices are not "seen" (neither in IOReg, nor in system profiler). And yes, I connected the additional power supply connector, ... and its basically working (win 10 / 10.10.5 no problems at all) .. for the time being I removed the card, .. temporary, I do hope so .. sooner or later I'll need the FW again, and I liked the combo USB/FW on one PCI Lane very much, any ideas would be really appreciated, thanks in advance Link to comment Share on other sites More sharing options...
