Hi, I've been struggling to get my UDEV rules to work properly to stop my tuner cards getting renumbered on reboot. I have to say, though I am getting thoroughly confused. My tuner setup is 2x Nova-HD-S2 cards which are DVS2 cards and a duel tuner Nova-T500. Trying to cobble together a usable set of UDEV rules, however, I don't seem to be able work out what is what. I have looked at the guide over at MythTV and here. I've also looked at the posts people have put on here. So, with the Nova-HD-S2 is listed udevadm info -a -p $(udevadm info -q path -n /dev/video0) gives me: Code: /devices/pci0000:00/0000:00:1e.0/0000:04:00.0/video4linux/video0
KERNEL=="video0"
SUBSYSTEM=="video4linux"
DRIVER==""
ATTR{name}=="cx88[0] video (Hauppauge WinTV-"
ATTR{index}=="0" However, it also has an entry as a DVB device. Code: KERNEL=="dvb1.dvr0"
SUBSYSTEM=="dvb"
DRIVER==""
looking at parent device '/devices/pci0000:00/0000:00:1e.0/0000:04:00.2':
KERNELS=="0000:04:00.2"
SUBSYSTEMS=="pci"
DRIVERS=="cx88-mpeg driver manager"
ATTRS{vendor}=="0x14f1"
ATTRS{device}=="0x8802"
ATTRS{subsystem_vendor}=="0x0070"
ATTRS{subsystem_device}=="0x6906"
ATTRS{class}=="0x048000"
ATTRS{irq}=="16"
ATTRS{local_cpus}=="ff"
ATTRS{local_cpulist}=="0-7"
ATTRS{dma_mask_bits}=="32"
ATTRS{consistent_dma_mask_bits}=="32"
ATTRS{broken_parity_status}=="0"
ATTRS{msi_bus}=="" I tried to set the adapter in the manner suggested for a non-dvb tuner and it didn't seem to make any difference. How should I set my tuners permanently? Any suggestions on how to get this right would be good. I also need some help with my dual tuner card.

I'm not familiar with either of the cards that your using so I'm not much help there.
I can tell you is that I've never had problem with a DVB side of the card changing id's, but I have had problems with the other tuner on the card.
I have a HD5500 card that the v4l side kept swapping from video0 to video1, and another mpeg tuner. I did write a rule for each one that linked video0 and video1 to a SYMLINK+="v4l/usbpvr" and SYMLINK+="v4l/HD5500
I would think that is the part of the problem that needs to be addressed. What output do you get when you run:
udevadm info -a -p $(udevadm info -q path -n /dev/video0)
And then:
udevadm info -a -p $(udevadm info -q path -n /dev/video1)
Thats where I'd start
Tim

Chris, Ok give this a try. in /etc/udev/rules.d create a file named 10-local.rules Code: KERNEL=="video[0-9]*", SUBSYSTEM=="video4linux", ATTR{name}=="cx88[0] video (Hauppauge WinTV-", ATTRS{vendor}=="0x14f1", SYMLINK+="v4l/Haup0"
KERNEL=="video[0-9]*", SUBSYSTEM=="video4linux", ATTR{name}=="cx88[1] video (Hauppauge WinTV-", ATTRS{vendor}=="0x14f1", SYMLINK+="v4l/Haup1" Reboot your machine and then do an ls -l /dev/v4l Hopefully you'll see something like this Code: drwxr-xr-x 2 root root 100 Nov 19 22:01 by-path
lrwxrwxrwx 1 root root 9 Nov 19 22:01 Haup0 -> ../video1
lrwxrwxrwx 1 root root 9 Nov 19 22:01 Haup1 -> ../video0 If you do it worked the rules worked. Then go into setup and use the following Code: /dev/v4l/Haup0
/dev/v4l/Haup1
as the paths to the devices. Good luck. Tim

Hi Tim, No such luck I'm afraid. ls -l /dev/v4l Code: 2012-11-20 18:53:25.762872 C [1924] Python Backend Connection Couldn't connect to backend [127.0.0.1]:6543
Couldn't connect to MythTV service for status
[tophee@Lust /]$ ls -l /dev/v4l
total 0
drwxr-xr-x 2 root root 120 Nov 20 18:53 by-path Cheers Chris

Chris, Try cutting down the length of ATTR{name}=="cx88[0] video (Hauppauge WinTV-" to ATTR{name}=="cx88[0] " I did have a problem with a long string in a rule as well. But the only other thing that I could find that is different between /dev/video0 and /dev/video1 is that ATTRS{irq}=="16" and ATTRS{irq}=="17" on the other, but I'm thinking that the irq could change at reboot time too. You could look into that. Can you post the output of Code: udevadm info --query=all --name=/dev/video0
udevadm info --query=all --name=/dev/video1 As well. If ATTR{name}=="cx88[0] " and ATTR{name}=="cx88[1] " doesn't work, remove them and just for grins use ATTRS{irq}=="16" and ATTRS{irq}=="17" instead. Tim

Hi Tim, No luck again with that. My confusion lies in the fact that I don't understand why the Nova-HD-S2 cards are seen as a 'normal' card but register as a DVB card and then how to keep their number consistent. I had another look at the dvb section of the MythTV UDev guide, I tried to cobble something together. So for the Hauppauge Nova-HD-S2 cards the lines I used was Code: SUBSYSTEM=="dvb", ATTRS{vendor}=="0x14f1", KERNELS=="0000:04:00.2", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter101/%%s $${K#*.}'", SYMLINK+="%c"
SUBSYSTEM=="dvb", ATTRS{vendor}=="0x14f1", KERNELS=="0000:04:01.2", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter102/%%s $${K#*.}'", SYMLINK+="%c" I was able to go into MythTV-Setup and use the 101 and 102 identifiers. Now just to set up permanent links for my Nova-T500D card. Thanks for your help Tim.

Chris,
Sounds good. At least it sounds like your making progress.

Well, I thought it was sorted, but it seems not. I ssh'd into my box to finish sorting my udev stuff out. However I was met with this: Code: Tuner Status:
--------------
Tuner 1 (DVB) on Lust : Idle
Tuner 2 (DVB) on Lust : Idle
Tuner 3 (DVB) on Lust : Idle
Tuner 4 (DVB) on Lust : Idle

raise MythError('Incorrect raw input length to DictData()')
MythTV.exceptions.MythError: Incorrect raw input length to DictData() I am expecting to see 8 tuners (two each) for the four tunes I have. It all seems to work, so what's happening? Regards Chris

I'm on LINHES 7.4 and getting the same errors when I ssh in. I have 2 Ceton Infinitv 4 PCIe tuners. One in my master backend and one in my slave backend. The tuner status shows good and seems to work on the master backend tuner but the slave backend tuner shows "error" under the status. They were all working and then all my upcoming recordings vanished and I couldn't schedule new recordings. Live TV worked and I could press R and record live TV. I deleted all the tuners, rebooted and added the tuners back in. That's when I came up with the ssh errors (that I've seen off and on while attempting to get these cards up) and got the errors on all 4 tuners on the slave backend. The upcoming recordings came back with the tuner re-add.
What should I check and what logs should I look at?
Thanks,
Joel

The problem is that they are changing device id's when you reboot. I key is to create a udev rule that will handle the id switch and point to the correct device. You can check out this post for some more additional information. viewtopic.php?f=21&t=22612

How can I completely get rid of the old tuner setup? I can go into the setup menu and delete all cards on my slave backend but then when I add the cards back it increments the tuner number so something is not getting cleared out. Do you know where the tuner number is stored? I'm all the way up to tuner 18 now from deleting and adding tuners.
I only have one tuner card in each box so do you think the UDEV rearranging issue can still mess with me?

After several deletes and adds and reboots... It works.
I deleted all tuners from the slave backend - not just the slave backend tuners but all tuners.
Rebooted slave and waited a little while.
Shutdown slave wait again.
Check master to see that all tuners are gone.
Reboot master. Wait.
Add tuners back to master & reboot again. Wait.
Start slave. Wait.
Add tuners to slave. Wait.
Reboot slave. Wait.
Shutdown slave. Wait.
Reboot master. Wait.
Start slave.
All seems fine now as far as the tuners go. Now I've lost all scheduled recordings for some reason. Yes, I added the input connections back to the tuners. What now???

Just saw your previous post. Thanks but I guess that part is fixed. Just need things to record now. This is where I lost my tuner config the first time. I deleted and re-added the tuners to get my recording schedules back. It worked but I lost the slave tuners. Now that I have all tuners I again have no upcoming recordings. I can watch TV and hit R to record and it works. Upcoming recordings says I have nothing scheduled.
