hey there,
I have one problem left on my El Capitan installation: USB 3.0 works fine with external powered USB drives. And additional I can plug in one more HDD without external power. Still everything works. But when I plug in another HDD without external power I get this message:
USB Device Needs Power
Connect "External USB 3.0" to a USB port on this Mac
The other USB drives still working. Because the built is all new, I can't really exclude mainboard or bios setup. I can exclude HDD...
"USB Device Needs Power" with more than one external USB HDD
