Il faut passer par les Options pour les développeurs, pour les activer si ce n'est pas le cas :

Paramètres → A propos du téléphone → Numéro de build → tapez 7 fois (!!)

Ce qui fait apparaître les Options pour les développeurs dans les Paramètres, pour accéder aux réglages USB :

Paramètres → Options pour les développeurs → Debogage USB

# apt-get install jmtpfs
$ jmtpfs -l

Penser à régler dans le Paramètres du FairPhone 2 → Options pour les développeurs → Sélectionner une configuration USB → MTP par exemple

$ jmtpfs -device=<busnum>,<devnum> ~/mtp
$ jmtpfs ~/mtp
$ fusermount -u ~/mtp
$ fusermount -uz ~/mtp
