Hello list,

after entering the command 

./szap -c channels.conf-dvbs-astra n24 -r

I got the debug output :
Apr  5 23:04:13 darkstar1 kernel: DVB: registering new adapter (TwinhanDTV 
StarBox DVB-S USB2.0 (VP7021)).
Apr  5 23:04:13 darkstar1 kernel: DVB: registering frontend 0 (Twinhan 
DST-like frontend (VP7021/VP7020) DVB-S)...

so, at the first glance it looks as if something is going wrong in

static int vp702x_fe_set_frontend(struct dvb_frontend* fe,
				  struct dvb_frontend_parameters *fep)

Is there any information availible to check what in this function should 
happen, e.g. from Twinhan data sheets ?

Thanks in advance and of course feel free to ask for more debugging 
information.
 
see you
 Uli
