Hola a todos!!
Soy nuevo en el foro pero no en el mundillo GNU/Linux en el que llevo 3 años aprendiendo y trabajando. Sin embargo, durante este tiempo no he sido capaz de resolver algunos problemas y por eso creo que es hora de solicitar vuestra ayuda. Uno de ellos es el siguiente:
Los programas (motion, xawtv, webcam-server) no son capaces de abrir la webcam (Trust Spycam 100), a pesar de que Linux la reconoce, carga los módulos y crea el enlace al dispositivo en /dev.
He probado a instalar los paquetes libv4l-0 y xserver-xorg-video-v4l como indica la Debian Wiki. Curiosamente, con Debian Squeeze y el kernel de serie (2.6.26) el único programa que funciona es webcam-server. Parece ser que el problema va de "palettes" pero desconozco que es eso.
Trabajo con Debian Squeeze y con el kernel 2.6.37. A continuación os posteo los logs y errores que me dan el kernel y los programas, así como adjunto el config del kernel:
