Caméra non détectée par le Rasberry pi 4 model B

Bonjour,

J’ai un problème : ma webcam (USB\VID_13D3&PID_5130&REV_1211) transformée un USB n’est pas reconnu par la fonction "

Code: Select all

fsusb

" de ma carte Raspberry pi 4 model B (même après un redémarrage ou elle est branchée) alors que elle est détectée instantanément par mon ordinateur (Windows - HP).

Auriez vous une idée d’ou pourrais venir le problème, et encore mieux une façon de le résoudre ?

Merci d’avance

Yaya

Vous avez plusieurs problèmes

  • fsusb n’a pas de sens sous GNUlinux, AFAIK; lsusb en a un

  • l’usb est demarrablle à chaud; vous devriez tenter de débrancher puis rebrancher votre camera USB, et de recupèrer les messages d’erreurs et de diagnostics par
    dmesg | tail -20
    ou
    dmesg # tout court (vous aurez les derniers messages de barnchement quand ça arrêtera de defiler)

  • vous postez (en vain) depuis 2 jours sous rapsberry.org : il serait plus efficace d’y poster en anglais (il y a davantage d’anglophones que de francophones et google translate fonctionne très bien du français (ou de l’azeri de l’Ouest bien écrit) vers l’omericoin) et il serait plus gentil, pour ceux qui creusent leur vieille cervelle (sous réserve d’existence) à la recherche d’une solution de savoir si cette solution a déjà été trouvée (les « double posts » sont parfois vus avec mépris, condamnant le double posteur à une éternelle absence de réponse: autant le signaler, et gagner quelque indulgence)
    Edité : corrigé grammaire

Bonjour dbrion06,

Merci beaucoup pour votre réponse rapide et vos conseils. Je suis désolé des mes erreurs, je ne connaissait pas les habitudes des forums en ligne. Je viens de supprimer mon poste sur l’autre forum.

Comme vous l’avez deviné, c’était bien une faute de frappe pour « lsusb ».

Je vous joins une copie du terminal après avoir débrancher/rebrancher ma camera et avoir lancé « dmesg ».

pi@raspberrypi:~ $

Je crois qu’il dit que le câble ne marche pas, alors qu’il marche à la perfection sous mon ordinateur Windows.

Peut être que la webcam n’est tout simplement pas compatible, dans ce cas, là ce n’est pas la peine de vous prendre la tête, je voulais juste avoir l’avis de quelqu’un qui s’y connait en Rasberry.

Merci encore de votre réponse rapide, et désolé de vous déranger encore une fois car je ne suis pas très doué.

me semble bien suspect:

If not, and you have 1-wire enabled, you will get false readings which will show as device names starting with « 00- ».

If you don’t have a Dallas 1-wire device attached, disable the 1-wire interface and you won’t get those messages.

recommande de ne pas (sauf bonne raison) activer le bus 1 wire (dans raspi-config: une case à (dé?) cocher) qui est une source de désordre… peut être alors que l’énumération se passera mieux (ça a marché pour moi; est ce généralisable?) .

deux détails:

  • la commande
    dmesg | tail -20
    ne donne que les 20 dernières lignes, suffisantes pour suivre la connection et l’eventuelle enumération d’un periferique usb et … moins rébarbatives qu’un historique complet (surtout si votre bus 1 wire a l’air loufoque)

  • il n’est pas nécessaire de retirer un post (tous les gens ne sont pas farouchement hostiles aux double posts). Une meilleure stratègie serait de traduire votre demande en anglais , pour avoir le maximum d’audience, et de faire profiter tout le monde d’une éventuelle solution (on n’en est pas encore là)

Rebonjour,

Voici ce que je reçois après avoir décocher la case « 1 wire » dans configuration du rasberry-pi (interface).

Encore une fois merci de m’aider,
Bonne journée.

La, je suis un peu sec .
Quelle alimentation avez vous (je me suis débarassé de pas mal de problèmes en surdimensionnant mes alims, qui sont peut être très bien pour des RPi sans périferiques)
Avez vous essayé un autre câble?

Bonjour,
Je n’est pas d’autres câbles, c’est ma première Raspberry pi.
Je tente de couper mon câble de webcam, lui ajouter un domino et booster le 5V avec ma carte Arduino.
Qui ne tente rien n’a rien, comme on dit,

Bonne journée.

JE vous avais posé deus questions, la première étant:

(à tester avant des modifs destructrictrices: vous bousillez un câble qui fait l’affaire avec un PC)

Bonjour,
j’ai testé mon système (vu votre message trop tard.) et il marche bien.

Merci pour votre aide

Mon alimentation était inclue dans le kit acheté.

au revoir.
