UDEV and new hardware?

UDEV and new hardware?

[raid517]

Hi I installed a modem driver for the Intel Corporation 536EP Data Fax 
Modem. But in order to use it I need to create a link from it (it is 
called 536ep0 in /dev) to /dev/modem. I need to do this specifically so 
that KPPP can see it.

The only thing is that everything in /dev/ gets deleted and rebuilt each 
time I reboot.

I have been led to believe (rightly or wrongly) that it is udev that is 
responsible for this. So the question is how can I make a symlink from 
/dev/536ep0 to /dev/modem that will remain in place and will persist 
even after a reboot?

Try adding:
  KERNEL="536ep0", SYMLINK+="modem"

to a rules file in:
  /etc/udev/rules.d/

Thanks I will certainly give that a go - although in the end I just 
wrote a small bash script and had it create the symlink and then added 
this to my system startup scripts. This should hopefully survive and 
upgrades to Udev in the future too. (Although having the capacity to 
create persiant 'on the fly' symlinks in /dev (just as I used to be able 
to do) would still be neat too.
