Détection de branchement USB avec Udev qui ne fonctionne pas

Bonjour à tous,

J'ai parcouru de nombreuses pages webs afin de trouver une solution à mon problème, en vain.

Je cherche à lancer un script que j'ai fait quand je branche un périphérique audio USB sur ma cible (embarquée, imx6, etc.). In fine j'aimerais lancer mon script lorsque n'importe quel périphérique usb de type audio (qui utilise snd-usb-audio comme driver) est branché.
Cependant, mon script n'est jamais lancé.
J'ai essayé de remonter le problème sous différents angles : détection par driver (snd_audio_usb), puis pour une carte son spécifique avec l'idVendor puis même carrément juste quand je branche n'importe quoi sur ma prise USB (clé usb, souris). J'ai essayé de placer mon script à divers endroits : /usr/bin, /etc/udev/scripts, /etc/udev/rules (juste à coté de la règle), /home/root/… ou encore /sbin. Sans succès.
Après plusieurs heures, je me dis qu'il y a peut-être un problème d'utilisateur mais ça reste une supposition et je ne sais pas trop comment gérer ça.

Si quelqu'un a une quelconque idée, ça serait merveilleux.

Je vous donne ce que j'ai écrit.

Fichier udev rules usb-audio.rules :

ACTION!="add", GOTO="End" SUBSYSTEMS!="usb", GOTO="End" ATTRS{idVendor}=="0d8c", RUN+="/etc/udev/scripts/usb-audio.sh" 
LABEL ="End"

J'ai tenté une version plus simple aussi :

KERNELS=="usb1",ACTION=="add", SUBSYSTEMS=="usb", DEVPATH=="/devices/soc0/soc/2100000.aips-bus/2184000.usb/ci_hdrc.0/usb1/1-1/1-1:1.0/sound/card1/pcmC1D0c", RUN+="/etc/udev/scripts/usb-audio.sh"

J'ai changé le devpath avec /devices/soc0/soc/2100000.aips-bus/2184000.usb/ci_hdrc.0/usb1/1-1/1-1:1.0/sound/card1/ ou même juste sans DEVPATH.
J'ai essayé sans "KERNEL" et avec un deuxième SUBSYSTEM : SUBSYSTEM=SOUND

Coté script, j'ai testé, il fonctionne si je l'appelle à la main.

Coté test j'ai ça :

root@machine:/etc/udev/rules.d# udevadm test usb-audio.rules

Avec cette étrange erreur à la fin (avec <------- rajouté). J'ai tenté de googler cette erreur mais sans succès.

Je suis infiniement désolée pour l'immense pavé (pour un premier post en plus…). J'espère ne pas m'être trompée d'endroit pour poser ma question.

Merci à vous :)

1°) tu remarqueras quand /etc/udev/rules.d les fichiers sont ranger par ordre de numero croissant pour qu'ils soient lu dans l'ordre

probable que ton usb-audio.rules soient pris APRES les autres
mais ce n'est peut-être pas ce que tu souhaites…

2°) d'après l'extrait

Reading rules file: /etc/udev/rules.d/usb-audio.rules
Reading rules file: /etc/udev/rules.d/usb-cameras.rules
Reading rules file: /etc/udev/rules.d/wayland-tsc2046-calibration.rules
rules contain 24576 bytes tokens (2048 * 12 bytes), 11956 bytes strings
1850 strings (23514 bytes), 1223 de-duplicated (12186 bytes), 628 trie nodes used
sd-device: syspath '/sysusb-audio.rules' is not a subdirectory of /sys
unable to open device '/sysusb-audio.rules' <------------- ERREUR

il semble vouloir chercher usb-audio.rules dans le /sys/
peut-être que tu ne devrais pas appeler ton fichier de la sorte, d'après ce qu'on trouve sur internet à propos du syspath non trouvé, c'est que le nom de la regle prête à confusion avec d'autres regles.

essai deja un truc plus perso comme par exemple : myusbaudio.rules

  Bonjour,
  Merci pour ta piste.
  J'ai tenté de changer le nom en my-usb-audio.rules puis d'ajouter "01-" au nom. J'ai toujours la même erreur. Il cherche toujours dans /sys
```
sd-device: syspath '/sys01-my-usb-audio.rules' is not a subdirectory of /sys
unable to open device '/sys01-my-usb-audio.rules'
```

La commande "udevadm test " attend un chemin vers un device en paramètre (udevadm test [options] [devpath]), pas un fichier .rules donc udev cherche un device qui s'appelle "usb-audio.rules" dans le dossier /sys d'où l'erreur (voir la page de man de la commande udevadm).
