Description Robert Hancock 2015-01-18 05:50:01 UTC 
Description of problem:
USB3 devices connected to USB3 ports are not recognized at all under the 3.18 kernel (no output in dmesg when device connected). These errors in dmesg seem related:

[    0.560912] xhci_hcd 0000:00:14.0: Max number of devices this xHCI host supports is 32.

Reported to LKML:

https://lkml.org/lkml/2015/1/18/17

Greg KH says "should be fixed in Linus's tree now and will be backported to
the latest 3.18-stable tree in a week or so."

Comment 4 Robert Hancock 2015-01-20 00:47:40 UTC 
Confirmed that USB3 devices work in 3.18.3-201.fc21. However, I did notice these errors in dmesg that I didn't get in 3.17:

[    0.881967] usb: failed to peer 1-9-port1 and 2-5-port1 by location (1-9-port1:none) (2-5-port1:usb1-port11)
[    0.881968] usb 1-9-port1: failed to peer to 2-5-port1 (-16)
[    0.881969] usb: port power management may be unreliable
[    0.881993] usb: failed to peer 1-9-port2 and 2-5-port2 by location (1-9-port2:none) (2-5-port2:usb1-port12)
[    0.881994] usb 1-9-port2: failed to peer to 2-5-port2 (-16)
[    0.882015] usb: failed to peer 1-9-port3 and 2-5-port3 by location (1-9-port3:none) (2-5-port3:usb1-port13)
[    0.882016] usb 1-9-port3: failed to peer to 2-5-port3 (-16)
[    0.882037] usb: failed to peer 1-9-port4 and 2-5-port4 by location (1-9-port4:none) (2-5-port4:usb1-port14)
[    0.882038] usb 1-9-port4: failed to peer to 2-5-port4 (-16)

I am not sure if they are related to this problem or not.
