ok this is really weird. before installing debian on my laptop i had ubuntu 5.10 on it, so to install the modem all i had to do was: download the driver from linuxant and do this: sudo dpkg -i hsf_{whatevercomesnext}.deb
and it did the job.

but i went do to the same thing with the debian modem and i got an error..
so how do install it??
plez help
