Re-bonjour, Jusqu'à très récemment, j'utilisais spca5xx pour ma webcam (une Logitech Quickcam Communicate STX). Or, depuis que j'ai installé les modules de ma carte TNT (em28xx et em2880-dvb), ce module ne fonctionne plus. Le résultat de dmesg est : usb 2-1: new full speed USB device using uhci_hcd and address 4 usb 2-1: configuration #1 chosen from 1 choice spca5xx: disagrees about version of symbol video_devdata spca5xx: Unknown symbol video_devdata spca5xx: disagrees about version of symbol video_unregister_device spca5xx: Unknown symbol video_unregister_device spca5xx: disagrees about version of symbol video_device_alloc spca5xx: Unknown symbol video_device_alloc spca5xx: disagrees about version of symbol video_register_device spca5xx: Unknown symbol video_register_device spca5xx: disagrees about version of symbol video_device_release spca5xx: Unknown symbol video_device_release Apparemment, ça viendrait d'un problème de compatibilité entre la partie videodev du noyau et celle fournit par Mercurial que j'ai du installer pour ma carte TNT. Qu'à cela ne tienne, j'ai donc essayé de recompiler spca5xx. # apt-get source spca5xx # cd spca5xx-20060501 # make Building SPCA5XX driver for 2.5/2.6 kernel.

Sinon, savez-vous si je pourrais essayer d'utiliser un autre module que spca5xx ? Merci d'avance. David.
