There is a simple solution to all these problems. Unfortunately
Ubuntu/Canonical Devs don't seem to find it appealing.

As mentioned above turning off USB autosuspend all together solves the
problems most people encounter. It's just Ubuntu/Canonical seem to
prefer having this enabled for the sake of being able to tell "we are
concerving energy" while sacrificing USB 2.0 speeds for most of us!

I am fully supporting conserving energy measures, but they need to work
100% reliable for everybody. At least in an LTS release!

You guys can turn it on again after Hardy! But let things work out of
the box for everybody in Hardy LTS!!!
