i am using Slackware 10.0 on kernel 2.6.7

i have a USB modem which connects on /dev/ttyACM0

there is no node like that so i made one by issuing the following command

# mknod /dev/input/ttyACM0 c 166 0

the modem connected just fine...

however the problem is that whenever i take a reboot the node gets disconnected ..what is the problem..

do i link it up with /dev/Modem????

I think it has to do with udev that 2.6 Kernels use. Either put a little script in rc.local that checks if the node is present and creates it if not, or configure udev. Its under /etc/udev.

I also need that node, but I'm using the 2.4 kernel series, so i just created it once.

Actually I think what you need is to add rules in /etc/udev/rules.d/udev.rules , but I'm not familiar with those kind of stuff.
I would just probably add something like this in my rc.local

Code:

 if [ ! -e /dev/input/ttyACM0  ]; then 
/bin/mknod /dev/input/ttyACM0 c 166 0
fi
