J’ai investi<\/s> claqu\u00e9 du pognon inutilement dans un mini clavier 3 boutons + un potar chez aliexpress<\/a>.<\/p>\n\n\n\n

Mon but est d’ajouter des fonctionnalit\u00e9s hors clavier \u00abstandard\u00bb pour actionner le micro quand je parle par exemple.<\/p>\n\n\n\n

Probl\u00e8me : toutes les touches du miniclavier sont vues comme des x<\/code>, et sont donc indif\u00e9renci\u00e9es.<\/p>\n\n\n\n
Il est visiblement n\u00e9cessaire de configurer\/corriger une couche plus \u00abbasse\u00bb du pilote de ce clavier.<\/p>\n\n\n\n
