At first try to disable PIN request only for one SIM (the second) and see, if You can change from first to that second SIM with James Bond method!
If that works: Heureka.

Now try to switch back with James Bond to the first SIM (with PIN code request). I am pretty sure, this will not work...
Now open a xterm (rootsh required) and type
sudo killall csd
This should bring up the PIN request for the first SIM, touch in Your PIN and another Heureka.

Choose, which method You prefer.

disclaimer:
this works for me with an adapter GDSI3G with similar switching method (11* or 22*)
