Hello

I am trying to use a TerraTec Cinergy DT USB XS Diversity USB key to
broadcast video on my private network.

I have followed tutorials from www.linuxtv.org but impossible to start
the device.

The key works correctly on Vista, so I am sure that the device is not
out of order.

My OS is a Fedora Sulfur ; kernel version : 2.6.27.9-73.fc9; my box is a 64bits

1) I describe hereunder all the steps I followed to (unsuccessfully)
start the key.

Everything is based on www.linuxtv.org tutos.

a) Installation of Mercurial and download of all the sources to
compile the modules.
b) As mentioned in the description of the key
(http://www.linuxtv.org/wiki/index.php/TerraTec_Cinergy_DT_USB_XS_Diversity#Firmware)
my device id is 0081 instead of 005a. Thus, I have modified (only
replace 005a by 0081) the file
linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h to take into account
this change.

Old line
==================================================================
 #define USB_PID_TERRATEC_CINERGY_DT_XS_DIVERSITY        0x005a
==================================================================
New line
==================================================================
 #define USB_PID_TERRATEC_CINERGY_DT_XS_DIVERSITY        0x0081
==================================================================

c) Compilation and installation

d) In /etc/sysconfig/modules, creation of the file load.modules. It contains :
====================================================
#!/bin/bash

modprobe dvb_usb_dib0700
====================================================

e) Reboot

The key is pluged and detected as mentioned by lsusb :

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
========================================================

A lsmod|grep dvb shows that all modules mentioned in the LinuxTV page
related to the Terratec key are loaded.

========================================================

I should have in my /dev directory a dvb entry with two devices
adapter0 and adapter1 with subdirectories linked to them. /dev/dvb is
missing and this is my problem.

If I could have some help I would appreciate a lot.
Thanks in anticipation.
