http://lwn.net/Kernel/LDD3/ may be a good start. But do you really need
to get into writing device drivers? (Some guy with an Indian name had a
Linux device driver book come out a few months ago too but I forget the
details. May be worth looking at; I never have.)

Which version of the kernel? (uname -r)

What modem is it? How does it plug in? Is it built in?

Which device driver are you trying to use for it? Where did you get it?
What `problems' occur - what do you do, what error messages appear?
