I've got an Intel Haswell-based system with a Gigabyte Z87X-D3H 
motherboard under Fedora 21. After updating to the 3.18.2-200 Fedora 
kernel, I noticed some errors in dmesg and at least some of my USB3 
ports don't recognize any USB3 devices plugged into them:

[    0.560838] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[    0.560912] xhci_hcd 0000:00:14.0: Max number of devices this xHCI 
host supports is 32.
[    0.560990] usb usb2-port2: couldn't allocate usb_device
[    0.561098] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[    0.561163] xhci_hcd 0000:00:14.0: Max number of devices this xHCI 
host supports is 32.
[    0.561239] usb usb2-port5: couldn't allocate usb_device
[    0.561344] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[    0.561409] xhci_hcd 0000:00:14.0: Max number of devices this xHCI 
host supports is 32.
[    0.561484] usb usb2-port6: couldn't allocate usb_device

This worked fine under 3.17. Is this a known problem?
