[mythtv-users] UDEV rules

Hoi Daryl,
I don't know, I just did. But then They are all analog.
I just used udevadm to get the info. Put it in a script to not all the
time type it
!/bin/bash
udevadm info --attribute-walk --path $(udevadm info --query path --name=$1)
and piped the output to my rules file, so I could copy and past them.
I found the difference between ATTR and ATTRS.
ATTR is in the node itself (basicaly kernel, subsystem, name and
index) and ATTRS is higher up the tree (which didn't exist with the
Winfast) The index by the way is an index of the nodes on one device,
so unusable to distinguish between identical cards. Maybe '[0]' in the
name is an usable enumerator. Else you have to use something like
path-id (the physical pci location) to distinguish.
The distinguising of the different devices on one card I do, as you
can see, on the name and partially on KERNEL, but I don't want to use
the counter in there, for that can change.
About the backend setup. I initially just typed them in the database
with phpmysql. On going to setup only one of the vbi's disappeared
once, but not a second time. It obviously had to learn. And they all
work (as before, the Winfst has no sound in Mythtv, but that's a bug I
filled. Mythtv tries to open a nonexisting dma-audio channel, closing
the cable connection on the way). Oh by the way I use 0.26 on gentoo
systems.
