Le pocket Pod est un multi-effet plutôt sympathique qui peut être facilement piloté via des logiciels propriétaires. Ceux-ci s’émulent plutôt bien avec wine mais il reste le problème du pilote pour aller parler avec l’appareil en USB. Il existe bien un pilote mais celui-ci n’est plus maintenu et ne compile donc plus. En particulier le paquet Debian est plutôt cahotique. A force de ne pas profiter pleinenement de mon pocket pod du fait de la contrainte de redémarrer sous un autre OS, je me suis forcé à me fendre d’un petit patch qui sera peut être utile à d’autres. Il ne restera plus qu’à charger le pilote via un modprobe line6usb :
