Post subject:  udev for pcHDTV 5500
I'm putting together some lines for manually configuring udev and I have a question. I currently only have 1 pcHDTV 5500 card, but I may want to get a second one in the future. I want to make sure I'm not messing that up.

For IVTV cards, the ATTR{name} is "ivtv? encoder MPEG". I'm assuming the ? is a wild card. The ATTR{name} for my pcHDTV card is "cx88_0_ video _pcHDTV HD5500 HD".

Is there somewhere I should be putting in a wildcard for the pcHDTV card so that when I add a second one there won't be a conflict?

FYI, this is what I currently have for my udev (not implemented yet...):
Code:
DRIVERS=="cx8800",ATTR{name}=="cx88_0_ video _pcHDTV HD5500 HD",KERNELS=="0000:00:0d.2",SYMLINK+="pcHDTV5500_1"
DRIVERS=="ivtv",ATTR{name}=="ivtv? encoder MPEG",KERNELS=="0000:00:09.0",SYMLINK+="pvr_350_1"
DRIVERS=="ivtv",ATTR{name}=="ivtv? encoder MPEG",KERNELS=="0000:00:0e.0",SYMLINK+="pvr_150_1"


Also, am I correct in assuming that after I make this change all I need to do is edit the capturecard table in the database and change the videodevices from /dev/video0, /dev/video1 and /dev/video2 to /dev/pcHDTV5500_1, /dev/pvr_350_1, and /dev/pvr_150_1?

Thanks!

This isn't working at all. I commented out the pcHDTV 5500 line for now to try and at least get the ivtv cards working. The system boots fine, but /dev/pvr* doesn't exist. Does udev throw up an error log somewhere that I can check?

Code:
SUBSYSTEM=="video4linux", ATTR{name}=="ivtv0 encoder MPG", SYMLINK+="pvr150"
I use the above in my MBE. In my SBE, I use:
Code:
SUBSYSTEM=="video4linux", ATTR{name}=="ivtv0 encoder MPG", SYMLINK+="pvr501"
SUBSYSTEM=="video4linux", ATTR{name}=="ivtv1 encoder MPG", SYMLINK+="pvr502"
As the HDTV cards use the DVB modules, I don't worry about udev rules for them (2 in each BE).

Cool, thanks for the information, cecil. That worked great. Much easier than finding out ID's and whatnot, too ;-).

Any chance in the future that you will support assigning an alias to a card in mythtv-setup and then automatically updating the database to reflect the alias in order to avoid problems like this?

Because I had trouble finding a good source to figure all this out I did a write up in the wiki with instructions. You can find it here if you need assistance:
