The dwc3 driver has seen a lot of development to add things like usb 3.1/3.2 support, USB-C and various power related stuff (being the PSU for a lot of devices now too) so TBH I'm not surprised there's regression here, the question here is what regressed it. You'd need to do a git bisect to work that out or in the very least a Fedora kernel 4.11.3-300 worked 4.11.4-300 it stopped because the difference between what ever F-24 kernel you have and what ever F-26 kernel is likely vast. If you're running the 4.11.8 kernel in F-26 have you at least tried the latest 4.12.8 F-26 kernel to see if that's the same/better/worse or a 4.13 rc6 F-27 kernel?
