Even in the absence of USB devices masquerading as PCI cards the<br>
loading of drivers, and therefore the binding of driver→device, is<br>
asynchronous, and therefore the assignment of DVB adapter IDs can vary<br>
depending on the order they get discovered in.<br>
<br>
Personally I deal with this using module options rather than udev:<br>
# cat /etc/modprobe.d/dvb-usb-dib0700.conf <br>
options dvb-usb-dib0700 adapter_nr=0,1,2,3<br>
options em28xx-dvb adapter_nr=4,5,6,7<br>
<br>
This ensures that adaptors 0-3 are always the dib0700 ones and adaptors<br>
4-7 are always the em28xx ones, but makes no guarantee about which<br>
dib0700 will be adaptor #3 etc. That's all I care about because the<br>
em28xx ones are HD capable while the dib0700 ones are not.<br>
<br>
This works well enough for me, but it does mean that if one adaptor is<br>
flakey then it can switch around (within its corresponding set of ids)<br>
on reboot.<br>
<br>
If your three classes of card use three different drivers then you<br>
ought to be able to arrange that the HP1250=adaptor#0, the<br>
winTV=adaptor#1 and the PCi800's are #2 and #3 (in some order).<br>
