I also have a running F26, thanks to Dennis for his tips.
@ Peter
[root@localhost ~]# lscpu
Architecture: armv7l
Byte Order: Little Endian
CPU(s): 8
On-line CPU(s) list: 0-3
Off-line CPU(s) list: 4-7
So all the CPUs are there and it's running as big.little, that seems
fine to me, if you load it up does it flip from the A7 processors to
the A15 or does it bring all 8 online?
I've compared this system with a running F24 system and load the
same kernel
modules via "modprobe".
Fedora 26
[root@localhost ~]# lsusb
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
So those two are the ones of interest, it is finding the USB3
controllers, I suspect you'll see the modules too (dwc3 or xhci
modules)
Fedora 24
The kernel version is more useful than the release.
[root@myodroid ~]# lsusb

The module "r8152" was manual loaded, but no Ethernet Adapter was found.
From what Dennis sent me from dmesg I see errors around LPM (Link
Power Management) and a quick google tells me it's not an unusual
problem [1] with USB-3 controllers.
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?
