USB sucks

The problem with USB is that it is a bit of an all-or-nothing
protocol.  Incremental development is hindered by not being able to
access the host side's primitives directly.  You just have to set it
up and let it go through a sequence.

It has this in common with physical real-time systems.  Because you
can't stop or slow time, often you just have to setup a test rig and
log the behaviour for later analysis.

Now, simulation does make this easier.. Is it possible to run the
linux side of the chain in a step-by-step way using qemu or so?  Seems
to be difficult to set up.  Probably logging[1] is the better
approach.
