Dear Cie,
in the upcoming version of HSNM, we followed last Ruckus directives to allow Unleashed firmware to work with it.
So summarizing:
Ruckus ZoneDirector 10.3 works
Ruckus ZoneDirector 10.4 works
Ruckus ZoneFlex (old standalone firmware) works
Ruckus Unleashed will work with the upcoming stable release.
