are dvb devices supported by udev, or do i have to write my own rules? i couldn't find any. is this maybe something that might be planned for the future?

i wonder how you made it work, without adding any rules by yourself. i filed a bug report yesterday and they too wondered, why dvb support is in the official tree but not in gentoo. so how did you do it?

The only thing I did was selecting the right drivers. Notice that you have to select two drivers for a single card. Namely the frontend and the card type. If everything is detected correctly you should have the following devices:
| Code: |
bash-2.05b# ls -l /dev/dvb/adapter0/
total 0
crw------- 1 root root 212, 6 Jan 1 1970 ca0
crw-rw-rw- 1 root root 212, 4 Jan 1 1970 demux0
crw-rw-rw- 1 root root 212, 5 Jan 1 1970 dvr0
crw-rw-rw- 1 root root 212, 3 Jan 1 1970 frontend0
crw-rw-rw- 1 root root 212, 7 Jan 1 1970 net0
|
Your device listing might be slightly different depending on the configuration of your DVB card. (I have a Hauppauge WinTV NOVA CI).

i had my tv card (pinnacle pctv sat xe) working, if - and only if - i was to run "MAKEDEVICES.sh" first and THEN loading the appropriate modules. the other way round does not work.
i still wonder, how UDEV can create your devices, if there are no rules defined for dvb device files.
btw. it's very untypical, that "world" get's read/write permissons on device files. that should be considered a security risk, at least i think so.

Put in your /etc/udev/rules.d/20-local.rules
| Quote: | | KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c" |
and in /etc/udev/scripts/dvb.sh
| Quote: |
#!/bin/sh
/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,' |
set the permissions in /etc/udev/permissions.d/20-local.permissions
| Quote: | | dvb/adapter[0-3]*/*:root:video:0660 |

I do not know udev very well but I thought it got most of its information from sysfs and rules are only needed to overrule the default names. Could it make a difference that I didn't compile the drivers as modules? |

nah!!! i don't get my devices... i'm getting really angry with this bull... no wonder noone wants to switch to linux. if installing a stupid tv card for the pc is that impossibly complicated, i wouldn't either, if it wasn't already too late for me  .
