Hi Peter!
hmm seems the read_status command works different than with the
dec2000t device.
Could you try the attached patch?
I applied the patch to the actual version of v4l-dvb drivers and loaded
it in debug-mode.
Now the output in the syslog by plugging in the DEC3000-s is the following:

That's fine so far.
The syslog-etnry while scanning is the following:

hrm, turned out to be a rather dumb bug. When dvbscan prepares the tuning it does:
SET_TONE(off), SET_VOLTAGE, SEND_DISEQC_MSG, SEND_BURST, SET_TONE.
Because the driver doesn't implemenent the send_burst method, dvbscan errors out
_before_ setting the tone, which results tuning to the wrong frequency ...
Try the attached patch, which implements a dummy send_burst function.
When I plugged it into my linux box and the modules where loaded I could
not change anything with the remove control on the reciever any more.
Even I could not turn it off! I must pull out the power supply to get it
back running standalone again!!
dvb-apps includes a program to reset the device to standalone mode.
Do you know the command?
ttusb_dec_reset (in dvb-apps/utils).
You need libusb in order to compile and use it.
