Registrace adaptéru DVB-T a udev

[oyankee]

Ahoj, mám menší problémek.
Po zkonfigurování  a nahrání modulů a firmwaru k čipu  ec168  mě zlobí udev.
Dříve se po zasunutí adaptéru do usb vytvořila složka /dev/dvb/adapter0  a v ní jednotlivá zařízení. teď se ale frontend vytváří přímo ve složce /dev/.
Jelikož všechny přehrávače ale hledají jen tu první možnost, není možné přehrávat.
Zkusím něco pohledat, ale radsi to sem pisu, protože asi nebusdu sám.

po zasunutí se v /dev/ vytvoří

dvb0.demux0
dvb0.dvr0
dvb0.frontend0
dvb0.net0

Nikde jsem nenašel, co s tím. link do /dev/dvb/adapter0 nepomáhá.

Zkusím toto znovu. Minule to dopadlo zle a systém nenastartoval. Třeba jsem se někde spletl.

Based on kernel version 2.6.31. Page generated on 2009-09-16 22:26 EST.

1   The DVB subsystem currently registers to the sysfs subsystem using the
2   "class_simple" interface.
3   
4   This means that only the basic informations like module loading parameters
5   are presented through sysfs. Other things that might be interesting are
6   currently *not* available.
7   
8   Nevertheless it's now possible to add proper udev rules so that the
9   DVB device nodes are created automatically.
10   
11   We assume that you have udev already up and running and that have been
12   creating the DVB device nodes manually up to now due to the missing sysfs
13   support.
14   
15   0. Don't forget to disable your current method of creating the
16   device nodes manually.
17   
18   1. Unfortunately, you'll need a helper script to transform the kernel
19   sysfs device name into the well known dvb adapter / device naming scheme.
20   The script should be called "dvb.sh" and should be placed into a script
21   dir where udev can execute it, most likely /etc/udev/scripts/
22   
23   So, create a new file /etc/udev/scripts/dvb.sh and add the following:
24   ------------------------------schnipp------------------------------------------------
25   #!/bin/sh
26   /bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'
27   ------------------------------schnipp------------------------------------------------
28   
29   Don't forget to make the script executable with "chmod".
30   
31   1. You need to create a proper udev rule that will create the device nodes
32   like you know them. All real distributions out there scan the /etc/udev/rules.d
33   directory for rule files. The main udev configuration file /etc/udev/udev.conf
34   will tell you the directory where the rules are, most likely it's /etc/udev/rules.d/
35   
36   Create a new rule file in that directory called "dvb.rule" and add the following line:
37   ------------------------------schnipp------------------------------------------------
38   KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
39   ------------------------------schnipp------------------------------------------------
40   
41   If you want more control over the device nodes (for example a special group membership)
42   have a look at "man udev".
43   
44   For every device that registers to the sysfs subsystem with a "dvb" prefix,
45   the helper script /etc/udev/scripts/dvb.sh is invoked, which will then
46   create the proper device node in your /dev/ directory.
