slmodem error
 

hi

I use the slmodem driver for my modem, in slackware I never had any problem with it ever, however I am having one in gentoo, which I can't understand:

when I go

I installs slmodem dirver, and creates the the following devices in /dev/
slusb0-3
slamr0-3

I use one of the slusb devices to connect to internet, via an application called
slmodemd

however If I go like this as I used to in slackware:
the shell says:
Although I know that the device was not being used,

another problem I think is related to udev, is that these devices the slusb ones are deleted everytime the system starts up, so I end up installing the driver again and again after every restart. How do I tell udev to spare these devices?
