OK, i figured out a bit how the module works looking at the sources; 
and, OOPS, the error below was my fault (i'm a newbie in dvb-s):
the smart card was inserted into cam in wrong side (but i can't 
understand why the cam complains for an error where the smartcard
is misplaced and not when it is not inserted at all...).

Now cam_set & cam_test seem to work fine, i can also explore cam menu
with cam_menu; however, channels aren't descrambled yet.

That's cam_set output:
Found 1CAM(s)
Using /dev/dvb/adapter0/ca0
Found 1 slots
CAM: ASTON, 01, 0100, 0100

and that's cam_test output:


./cam_test -q 10834000 -l V -r 27500000 -t 430 -i 1104 -d
Warning: TP already defined:

CAM Test: 0x450 0x1a4 0x1ae 0x0 0xffff 0x11


note: the output of cam_test is the SAME, being the smartcard  
in the cam or not. 

Using cam_menu, i verified that the cam knows my
smartcard is enabled to see that channel...


Sorry for my english,
and thanks for any help!
