I am wanting to use XPression for a show coming up, since everything is already built, but the presenter has requested a clicker in order to advance slides on their own. Is there a way to use a "Kensington Expert Wireless Presenter" with XPression to do this? 

Simply plugging in the USB stick on the system does not work. Is there a way to advance to the next item in the list with this product, or another solution?

I don't own this device but the first thing I would try is to create a Keyboard/GPI shortcut with "Page Down" set as the hotkey for a "Take Next" sequencer command.
