Estoy intentando que un dongle USB 3G funcione en una Raspberry Pi que ejecuta Raspbian Wheezy, usando un script llamado sakis3g.
Sin embargo, al intentar hacer esto, sigo teniendo problemas: cuando intento conectarme al dispositivo USB, el script imprime "Instrucción ilegal" y no avanza. He publicado unpregunta sobre esto en el sitio Raspberry Pi Stack Overflow, y se le dio una guía para intentar seguir (respuesta de BigCowPi). Sin embargo, como dije allí, cuando intento ejecutar lsusb(lo primero en esa guía), todavía genera "Instrucción ilegal" y no avanza.
Intenté reinstalarusbutilsylibsub-1.0-0para armhf, pero esto no ha ayudado a mejorar la situación.
También vale la pena mencionar que no tengo acceso a Internet en este momento, por lo que he estado descargando paquetes para instalarlos y usando dpkg, en lugar de algo más simple como apt-get.
No logré obtener una respuesta del sitio de Raspberry Pi, por lo que pensé que valdría la pena preguntar aquí, ya que de todos modos podría ser un problema más relacionado con Linux.
Salida de strace lsusb
Según lo solicitado por @Flup, aquí está el resultado de strace:
