anyone else getting an error about usb devices needing power? i've got a usb key which I'd used to install el capitan with but it just won't function in the os itself strangely enough
other devices, including external hard disks, function okay though i don't think they're functioning at usb3 speeds

RehabMan: I guess I need to do custom UsbConnectors at some point, just to get rid of the empty ports. Goes on the issue list...
not yet, slowly digesting your el capitan usb thread and will take it up sooner or laterRehabMan said:Did you patch DSDT correctly?
(injecting power properties).
Did you configure USB ports correctly?
(USBInjectAll + custom configuration with correct UsbConnector for each port)
all 3 options enabledgfoury said:What are your USB settings in BIOS?
I'm only injecting USB properties for XHC (the others are commented out), so if your devices are ending up on EHC1, I don't know what will happen--possibly the kind of complaint you're getting.

so far so good anerik no more usb errors with any of my devices so far
