Hey, don't use the same value for NAME _and_ SYMLINK. :)

Thanks for the tip - I should've realized that was silly. I've tried it with
other text there (and just re-tried it), though, and it still doesn't work.
I just tried this:
BUS="usb", KERNEL="irda[0-9]", NAME="%k", SYMLINK="IRdongle"

Is there really a /sys/class/usb/irda* device in sysfs for your device?
I didn't think the irda driver used the usb major number. Where in
sysfs does the "dev" file for this device show up (it should be
somewhere in /sys/class/. If not there, that's why this isn't working.

It's got information under /sys/class:

Realizing I may be an idiot, I just tried:
BUS="net", KERNEL="irda[0-9]", NAME="%k", SYMLINK="irdongle"
but that didn't work, either.
Thanks for the help so far!
Chris.

Okay, thanks - I didn't know that.
Is there anything I can do to get udev (or whatever is responsible) from
deleting the nodes I put in by hand? Is there a "don't delete list
somewhere?"
Thanks.
Chris.

I don't understand, why do you want to keep device nodes that are never
used?
Anyway, that's a distro specific issue, I suggest asking the proper
distro mailing list for how to do that.
Hope this helps,

I'm sorry: one more message. I mis-typed what I want - and I see from your
message that I need to clarify my problem. I meant:
"Is there anything I can do to get udev (or whatever is responsible) to NOT
delete nodes I've added by hand?"
The problem is that when I go to sync my Palm Pilot with jpilot, udev (or some
other software) has often deleted the /dev/irda0 node I created for jpilot to
talk through. This means that almost every time I want to sync my Palm I
have to create /dev/irda0 by hand because something has deleted it. I want
to stop whatever is automatically deleting the nodes I've added by hand (in
this case /dev/irda0). It's really annoying!
Thanks.
Chris.

Well, the kernel device that caused that device to be created was
removed from the system (that's what happens with palm devices.) So
udev _has_ to delete the device node as if it didn't, it would be a
security problem.
Just have udev create the node you want for your pilot, and then you
don't have to do anything by hand :)
thanks,

Does it really get deleted without a reboot? If your system use udev,
than there is a high chance that the /dev directory is on tmpfs which
will not survive a reboot.

I see what you're saying, but I sync my Palm via infrared! The device
that's irda0 is the USB dongle that gives my PC the ability to talk to
the Palm via IR. It's ALWAYS plugged in!
I think Kay Sievers may have pinned it down with my /dev system being
on a tmpfs which doesn't survive reboots. It looks like the deleting
of /dev/irda0 is because of this (I don't sync very often). Now it
looks like I will have to investigate what builds the /dev system upon
boot - so I can modify it to add my irda0 node. What a pain.
Thanks.
Chris.
P.S. - mount tells me:
none on /dev type tmpfs (rw,size=5M,mode\a55)
