This resembles very much to these bugs:
https://bugzilla.redhat.com/show_bug.cgi?id=1189107
https://bugzilla.redhat.com/show_bug.cgi?id=1257131

Sounds like may try to
- add xhci_hcd.quirks=262144 to you kernel boot parameters (in 
grub2-efi.cfg)

- build a custom kernel with the patch from
https://bugzilla.redhat.com/show_bug.cgi?id=1257131#c15
applied
