Bonjour,
Je viens de faire l'acquisition d'une Webcam Plus. C'est mon seul et pr�mier
device USB.
L'utilisation de camstream ou caminfo ( en utilisateur standard ) g�le
compl�tement le PC. ( clavier bloqu�, impossible de se connecter avec un
minitel sur com2), oblig� de faire reset !!! Au bout de 3 manip, je cherche
de l'aide pour ne pas flinger ma configuration.
Voici donc mes r�flexions, corrigez en cas d'erreur :
--------------------------------------------------------------------------------------------------------
-Suite � la lecture de diff�rentes documentation, il apparait que le
hotplugin n�cessite l'ajout d'une couche de scripts et la bonne configuration
du noyau pour lancer l'utilitaire hotplug ( de m�moire).
- l'erreur suivante est-elle li�e au fait que le hotplug n'est pas mis en
place et que l'on d�connecte / reconnecte la cam�ra ?

Il existe un daemon usb qui lanc� usbd, la doc concernant cet utilitaire est
sommaire et prouve pas l'interet de ce programme. Je ne l'ai pas lanc�.
Erreur ?
---------------------------------------------------------------------------------------------------------------
Le hotplug n'�tant pas ma priorit�, je voudrais avoir des images pour
v�rifier le bon fonctionnement de la cam�ra et des ports USB. Donc halt du
syst�me et rechargement. Vous trouverez ci-dessous les messages lors du
chargement ainsi que quelques fichiers de configuration.
MDK 8.0 et noyau 2.4.10 ( la r�action en 2.4..9 �tait le m�me).

Le chargement semble donc s'effectuer correctement.
Un xawtv permet de visualiser les chaines TV.
Comment trouver device utilis� par la cam�ra ?
Un caminfo g�l� le syst�me, xawtv -c /dev/video1 idem.
Comment emp�cher le gel du syst�me ?
Je cherche une piste.
Cordialement.
