MIDI controller not returned by MidiInput::getDevices()


while using apps built with JUCE, one of my MIDI controller (Evolution UC-33e) never shows up in the list of available MIDI inputs returned by MidiInput::getDevices(). The same controller is recognized and works fine in Cubase. Does someone have an idea on how to fix this issue? I am using JUCE 5.4.1 and Cubase 7.5 (64 bits) on Windows 7 SP1. I also made sure to install the latest driver for the UC-33e.
