<p class=MsoNormal>All,<o:p></o:p></p>
<p class=MsoNormal>I have tried to resolve this on the “Linux-DVB”
and Hotplug “UDEV” lists, now trying on the Fedora Forum (<a
href="http://forums.fedoraforum.org/showthread.php?t=160840"><span
style='color:windowtext;text-decoration:none'>http://forums.fedoraforum.org/showthread.php?t=160840</span></a>)
so thought I might as well ask here as it’s my desire for a working
MythTV setup thats causing the issue!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a problem whereby I need to pin a specific DVB PCI
card by PCI slot/PCI address to a dvb node (/dev/dvb/adaptor*), at the moment
my system has two (almost identical) cards from the same manufacturer
(TechnoTrend/Hauppauge), however one is DVB-T and one is DVB-S. <br>
As far as udev is concerned they report similarly, so things get really messed
up when on one boot, the DVB-T is /dev/dvb/adaptor0 and the DVB-S is
/dev/dvb/adaptor1 on the next boot they are reversed (the DVB-T is
/dev/dvb/adaptor1 and the DVB-S is /dev/dvb/adaptor0).<br>
<br>
I am really not passionate about whether I use UDEV or load modules manually to
achieve my objective of persistent mapping of PCI Slots/PCI addresses to DVB
node’s. The latter is probably preferable, as I have been bugging guys on
the UDEV mailing list for months, and I just can’t get things to play
nice in Fedora, although I am assured things work in Gentoo.<br>
<span style='color:black'><br>

style='color:darkred'>udevinfo -a -p $(udevinfo -q path -n

response is - <o:p></o:p></span></p>
