All,
I have been playing with udev as I need to pin specific identical DVB cards
to specific nodes, mixing DVB-S and DVB-T is bad!
I have found how to identify cards etc. but getting the rule right is
confusing me. I am running Fedora Core 5 and have the following standard
rule in "/etc/udev/rules.d/50-udev.rules" -

SUBSYSTEM="dvb", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf
dvb/adapter%%i/%%s $${K%%%%.*} $${K#*.}'", NAME="%c", MODE="0660"
 
The closest I got to getting things working was by substituting
"dvb/adapter%%i/" with "dvb/adapter5/", thus forcing the adapter to
/dev/dvb/adapter5, rule below -

BUS="pci", ID="0000:01:06.0", SYSFS{device}="0x7146",
SYSFS{vendor}="0x1131", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf
dvb/adapter5/%%s $${K%%%%.*} $${K#*.}'", NAME="%c", MODE="0660"

Unfortunately that changed the tree/node structure from the norm -
 /dev/dvb/
 `-- adapter5
     |-- ca0
     |-- demux0
     |-- dvr0
     |-- frontend0
     `-- net0
 
To -
 
 /dev/dvb/
 `-- adapter5
     |-- 0dvb
     |   `-- adapter5
     |       |-- ca0
     |       |-- demux0
     |       |-- dvr0
     |       |-- frontend0
     |       `-- net0
     `-- event3dvb
         `-- adapter5
             `-- event3
 
I think the problem I am having is that the original rule is based on the
top section of my "udevinfo -a -p $(udevinfo -q path -n
/dev/dvb/adapter0/frontend0)" response, my rule is based on the second
section, thus introducing additional layers as it's further down the
hardware/kernel stack?

My "udevinfo -a -p $(udevinfo -q path -n /dev/dvb/adapter0/frontend0)"
response is as follows -

  looking at device '/class/dvb/dvb0.frontend0':
    KERNEL="dvb0.frontend0"
    SUBSYSTEM="dvb"
    SYSFS{dev}="212:3"

  looking at device '/devices/pci0000:00/0000:00:10.0/0000:01:06.0':
    ID="0000:01:06.0"
    BUS="pci"
    DRIVER="budget_ci dvb"

    SYSFS{vendor}="0x1131"

    SYSFS{msi_bus}="1"
    SYSFS{broken_parity_status}="0"
    SYSFS{enable}="1"
    SYSFS{modalias}="pci:v000010DEd0000026Fsv00000000sd00000000bc06sc04i01"
    SYSFS{local_cpus}="1"
    SYSFS{irq}="0"
    SYSFS{class}="0x060401"
    SYSFS{subsystem_device}="0x0000"
    SYSFS{subsystem_vendor}="0x0000"
    SYSFS{device}="0x026f"
    SYSFS{vendor}="0x10de"

Can anyone advise of the correct rule?

Thanks in advance!
