[Jde] Problema con driver Firewire

Yo tuve muchos problemas con el driver firewire. Utiliza librerías
firewire relativamente antiguas (la versión 13).

Te adjunto un driver que medio trampe para que utilizará las librerías
más modernas de firewire (la versión 22). No está hecha la parte de leer
el fichero de conf, y únicamente registra 1 cámara firewire.

Para cargar el módulo únicamente es necesario poner esto en jde.conf

driver firewire_22
end_driver

A ver si tienes suerte y así te funciona.

Un saludo!
