Antti,

If you do decide to take on analog in dvb-usb and use em28xx as a
model, bear in mind that the locking between analog and digital is
*totally* broken.  You can open both the analog and digital devices
simultaneously, causing completely unpredictable behavior.  I'm just
mentioning this because this is something you should *not* model after
em28xx, and because it's a huge headache for real users (lack of
locking causes all sorts of end-user problems in MythTV and other
applications that support both analog and digital).
