The USB3.0 has become USB2.0 after upgrading from PB4 to PB5.

USB 3 is being seen as normal. see if you can mount a pen drive or try a mouse if it doesn't work then try downloading MaciASL then patch a DSDT using PJALMs Patches I did this in 10.10 and still remains working in 10.11 good luck. http://pjalm.com/repos/gigabyte/

Apple has changed USB 2 and 3 in 10.11 it's normal.
 
This is what my USB 3 is being shown as in 10.11 Beta 5.

All USB3.0 port can work, but all display as USB2.0. I have a external HD drive, which is USB3.0. I made a test via that external HD drive and it indeed displays as USB2.0 (up to 480 MB/s) rather than USB3.0.

PS: The external HD drive used to display as USB3.0 (up to 5 GB/s) before.
