USB 3.0 drives not recognized by OS X 10.11
When Insert USB 3.0 drives they do not work, but USB 2.0 drives work just fine.
Yosemite had no problems with usb 3.0 drives for me.
Only using usb 3.0 ports 4 on M/B and 2 on top of case with USB 3.0 header on M/B
i see you have a gigabyte board
you didn't change the echi xchi settings in the bios right
that will make usb 3.0 to stop working
also the same goes for usb 2.0
changing those setting can make only one of the to work
depending in the combination you use in the bios
you have to use the setting that makes both of them work
i will say rest the bios to default
then change everything you need to change back except
the echi and xchi
one last thing
is your Yosemite a distro
or did you downloaded yosemite from the app store and crete your own installer
if you are using a Yosemite distro maybe the usb 3.0 drivers are already included in the image
for Yosemite downloaded from the app store you have to add the driver yourself
you need this file for usb 3.0 support

i also have a gigabyte motherboard
i haven't tried el capital yet
my only doubt is that
usb 3.0 should work in usb 2.0 just at lower speed
do you those usb 3.0 formatted as ntfs and maybe that's why the system don't see the device
plug the usb 3.0 and go to disk utility and see
anyway good luck
maybe apple did change something
i will come back later
