Exactly, for the *runtime* dependency, that would be a *recommand* and
we detect if libusb is present or not. But  that's really up to the
packager to decide how he does it. Each distro might have their own
policies.

As the upstream developer, you should let the user decide if he want UST
support or not. I might be building an embedded system were space is a
constraint and I would want to only  have the kernel tracer and not
bother with he userspace one.
