Hello,
I have a mouse and keyboard plugged into a 4-port USB 2.0 hub, plugged into a
10-meter extender (which seems to also appear as an USB 2.0 hub).
When this combination is plugged into "Etron Technology, Inc. EJ168 USB 3.0 Host
Controller (rev 01)", it fails to work:

Not a bug, this is how USB works. Your first hub really does not have
enough bandwidth for that device. Well, we think it doesn't, the
calculation for that is really really tricky and we error on the side of
"let's not take the risk and just disable the device to be safe".
Get a better hub :)

But why the calculation is different when the hub is plugged into the onboard
USB 2.0 controller -- and there it works?
I hope you don't take this as a bug report to make it stop working there as
well. :)
If it's because the Etron controller is USB 3.0, and the higher speeds are
somehow accounted for in the bandwidth calculation, that doesn't seem right,
since both of the plugged in downstream hubs are 1.1/2.0-only.

You have more hubs in the way, they take up bandwidth on their own just
sitting there.

USB 2 hubs plugged into a USB 3 controller require horrible things to be
done on the wire to make everything work properly. Part of that
horribleness is bandwidth determination that we honestly are not the best
at in Linux. But again, we err on the side of safety, which means we
guess on the low-end compared to other operating systems.
