En exécutant la commande

$ ./ioiodude --port=/dev/IOIO0 versions

j'obtiens cette erreur :

La solution que j'ai trouvé, sur la liste ioio-users c'est de désinstaller la bibliothèque “libjna-java”:

sudo apt-get autoremove libjna-java

Mettre à jour le firmware de la IOIO-OTG:

D'origine j'ai:

$ ./ioiodude --port=/dev/IOIO0 versions
