Rajeev,

The difficulty of interfacing a new piece of h/w to GNU Radio varies
widely depending on the complexity and sophistication of the h/w and
what you want it to do.  In the more simple cases, it's probably on
the order of 500 lines of code.  This assumes you've already got some
kind of Linux driver that knows how to talk to the device.
