If you intend to use the standalone driver alongside a current v4l-dvb 
snapshot, then you have to also make that v4l-dvb snapshot visible to 
the pvrusb2 driver compilation process.  Please scan through:

http://www.isely.net/pvrusb2/setup.html

You have a number of choices here.  You could for example just tweak the 
pvrusb2 driver version within the v4l-dvb snapshot and use that 
(currently it is fully up to date).  Note also that if you don't use a 
v4l-dvb snapshot, then you must ensure you have the correct kernel 
CONFIG settings enabled.  Just read the page referenced above then go 
back and look at what you tried.  If you still can't figure it out, drop 
me a note and I'll try to help some more.
