I wonder if there may be something else going on here, maybe
Fedora-specific, or flakey hardware? I'm running self-compiled 4.0.5 (with
the Gentoo patchset) on my ECS Liva and I've never had anything that looked
like USB issues. I did verify that line in the source code is unmodified by
Gentoo (mine still says n=32). Now granted, I've only tried one remote
receiver and USB keyboard and one or two flash drives so my experience is
not exactly broad, but a number of other people picked up an ECS Liva for
use as a MythTV frontend and have virtually zero complaints about them. The
only way to really test it is to install a different OS on it, which I
gather you're unwilling to do.
