In Rekordbox's case Pioneer have restricted the jogwheel mapping to Pioneer hardware only. So, you pretty much need Pioneer hardware to use Rekordbox. And seeing as Pioneer decks are almost industry standard in clubs and you need Rekordbox to organise your playlists, they have the DJ hardware market sewn up. Which is very frustrating because Rekordbox has to be the most resource intensive (& therefore inefficient) DJ software available.
