I have two PCI cards and a dual tuner USB..

I was unhappy with the order the tuners were added, mostly because it
was unpredictable..

I use the following solution:


options cx88-dvb adapter_nr=0,1
options dvb_usb_dib0700 force_lna_activation=1 adapter_nr=2,3

This ensures the internal PCI (cx88-dvb) are adapters 1 & 2, and the
USB device is adapters 3 & 4.

This was an easy solution, but you will need to follow the wiki


if you want more control.  For example, I have two cards using cx88-dvb,
the order is not defined in this context, though it is consistent.
(Its actually defined by the order of the PCI slots, and I can reverse
them by
 reversing the cards..)

Good luck.
