Llevaba tiempo queriendo conectar mi pequeño portatil a la TDT (televisión digital terrestre) así que me agencié una tarjeta usb híbrida. En los foros a mucha gente le funcionaba, e incluso desde Feisty se la reconocía con sólo enchufarla.
Pero cuán caprichoso es el destino, cuando conecto la mía y no funciona. Tras un pequeño estudio, llego a la conclusión de que los amigos de Freecom se les ha ocurrido la idea de cambiar el chip de la tarjeta. Ahora trae un Realtek.
¿Cómo instalar los drivers?
Para comprobarlo hice un:
lsusb
y el resultado fué:
14aa:0160 Avermedia (again) or C&E
Pues nada, tendremos que trabajar (qué pena;-)
Lo primero que deberemos hacer es activar los repositorios Universe-Multiverse de nuestra Ubuntu, para tener disponible todo el software necesario durante la instalación de apt-get.
Ahora instalamos los paquetes necesarios:
sudo apt-get install build-essential
sudo apt-get install mercurial
sudo apt-get install linux-headers-$(uname -r)
Ahora vamos a utilizar la ayuda de los señores de linuxtv. Nos descargaremos un directorio completo de su web. Desde nuestra carpeta de usuario, tecleamos:
hg clone http://linuxtv.org/hg/v4l-dvb
Este comando creará una carpeta llamada v4l-dvb en nuestra carpeta de usuario.
Hasta aquí todo bien. El problema está en que aunque v4linux tiene un montón de drivers, el nuestro no aparece, por lo que tendremos que modificar algunas cosas:
Descargamos el archivo con los drivers de:
RTL2831lo descomprimimos y los archivos de la carpeta los copiamos en:
~/v4l-dvb/linux/drivers/media/dvd/dvd-usb
Ya tenemos los drivers añadidos l listado de v4linux, ahora hay que explicarselo al config, para que los tenga en cuenta, editando Makefile:
sudo gedit ~/v4l-dvb/linux/drivers/media/dvd/dvd-us/Makefile
y añadimos estas líneas, al principio:
dvb-usb-rtl2831u-objs = math_mpi.o foundation.o demod_rtl2830.o tuner_demod_io.o tuner_mxl5005s.o mt_spuravoid.o \ mt_userdef.o mt2060_basic.o tuner.o MT2060Tuner.o rtd2830.o rtd2830u.o obj-$(CONFIG_DVB_USB_RTL2831U) += dvb-usb-rtl2831u.o
luego hacemos lo mismo con el Kconfig:
sudo gedit ~/v4l-dvb/linux/drivers/media/dvd/dvd-us/Kconfig
En donde añadiremos:
config DVB_USB_RTL2831U tristate "Realtek RTL2831U DVB-T USB2.0 support" depends on DVB_USB help Realtek RTL2831U DVB-T driver.
Ahora volvemos a la carpeta del kernel de v4l:
cd ~/v4l-dvb
y hacemos un config:
sudo make config
Tras contestar un montón de preguntas:

Ya tenemos configurado el driver. Ahora hay que fijarlo:
sudo make sudo make install
(se puede poner sudo make&&make install, pero a mi me gusta ir poco a poco)
y por fín lo instalamos
modprobe dvb-usb-rtl2831u
Ahora una comprobación de rigor:
lsmod | grep dvb
y tiene que aparecer:
dvb_usb_rtl2831u
dvb_usb
dvb_core
dvb_pll
i2c_core
Llegados a este punto, sól queda una cosa, reiniciar.
REINICIAR?
Pero si en Linux no se reinicia!!!! El tema es que hemos tocado el núcleo y tenemos que hacer que los nuevos drivers se carguen con el nucleo. Se puede hacer sin reiniciar, pero eso tocará otro día.
sudo reboot
En cuanto ingreses en tu sistema la tarjeta se pondrá a parpadear como una loca.
