Writing device drivers

[shampavman]

Hi all,

I've followed up LDD3 and started off with writing device drivers . As 
usual i've started with char drivers given in that book and also started 
to make minor modifications to learn it better and so on.

Now i would like to know how to take it forward and start writing 
drivers for a profession.
I know its too early to call myself a guy writing device drivers but how 
do i take if forward from here so that i can become one.

Is the only solution to pick up a device which does not work on linux 
and get it working? Are there any other ways as well?
