 |
|
Bonjour,
- Voila, je rencontre une problèleme assez bizarre. En faite je me demandais si y'avais quelques chose de spécial à activer dans le kernel pour l'utilisation d'un HUB usb2.0. Car en faite, visiblement il marche bien sauf avec ma webcam.
- Si je branche ma cam directement sur un port usb elle marche très bien, hors si je la branche sur le hub la elle ne veut rien savoir 
Par exemple avec spcaview (l'utilitaire fourni par les drivers spca5xx) je me retrouve avec ceci :
| Code: |
Spcaview version: 1.1.4 date: 27:11:2005 (C) mxhaard@magic.fr
Initializing SDL.
SDL initialized.
bpp 3 format 15
Using video device /dev/video0.
Initializing v4l.
ERROR opening V4L interface
: Function not implemented
|
Or je le repette si je branche la cam directement sur un port usb (sans passer par le hub) ca marche impecable.
La deuxieme chose de louche, c'est que tous mes autres periphs usb (clés, appareils photos numeriques etc..) passe très bien, même avec l'usb 2.0.
Donc voila je fais appel à vous !
voila quelques infos :
| Code: |
medion nicolas # lspci | grep USB
00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f)
00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f)
00:03.2 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f)
00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller

As tu essayé de branché ta webcam seulement sur ton hub USB 2.0 ?
il se peut que la webcam en question est besoin d'un bus USB a elle toute seule.

oui, et la aussi toujours le même problème.
J'ai vu quelques options dans le kernel, par exemple :
| Code: |
<*> EHCI HCD (USB 2.0) support
[ ] Full speed ISO transactions (EXPERIMENTAL)
[ ] Root Hub Transaction Translators (EXPERIMENTAL)
|
| Code: |
<*> Support for USB Gadgets
[ ] Debugging information files
USB Peripheral Controller (Dummy HCD (DEVELOPMENT)) --->
Dummy HCD (DEVELOPMENT)
|
En compilant les 2 première options, je vois une évolutions : en faite quand je lance l'utilitaire spcaview il bloques au niveau de l'initialisation de v4l. Cependant j'ai plus le message d'erreur. Alors est-ce bon signe ou pas, doit-je regarder dans cette direction la ? |
