That example worked for me in both 2.5 and master (aka 2.6).
In both master and 2.5, by default loadusr expects the comp to have the
same name, as specified by hal.component("compname"), as the name of the
file. Possibly that's the problem you're seeing?
You can override the name that loadusr expects using the -Wn argument to
loadusr. See the halcmd manpage or "halcmd help loadusr" for details.
