[linux-dvb] DVB-S2 frontend doesn't work!

Hi everyone!

I have a problem with my HVR-4000 card.

I installed the firmware cx24116 find on
http://tevii.com/Tevii_linuxdriver_0815.rar
sudo cp tevii_linuxdriver_0815/fw/dvb-fe-cx24116.fw
/lib/firmware/dvb-fe-cx24116-1.23.86.1.fw
sudo ln -s /lib/firmware/dvb-fe-cx24116-1.23.86.1.fw
/lib/firmware/dvb-fe-cx24116.fw

I installed S2API find on http://linuxtv.org/hg/~stoth/s2/

make & make install
cp ./linux/include/linux/dvb/* /usr/include/linux/dvb/

and I installed szap-s2 find on http://mercurial.intuxication.org/hg/szap-s2

Every seems to be ok...
I can tune an DVB-S signal, but not DVB-S2...
I try to tune a DVB-S2 signal with a symbols rate of 75335000 (>45000000)
and I have this error message with dmesg :

[ 450.409150] DVB: frontend 0 symbol rate 75335000 out of range
(1000000..45000000)

So I try dvbsnoop to see the frontend information :

# dvbsnoop -s feinfo
dvbsnoop V1.4.50 -- http://dvbsnoop.sourceforge.net/
---------------------------------------------------------
FrontEnd Info...
---------------------------------------------------------
Device: /dev/dvb/adapter0/frontend0
Basic capabilities:
Name: "Conexant CX24116/CX24118"
Frontend-type: QPSK (DVB-S)
Frequency (min): 950.000 MHz
Frequency (max): 2150.000 MHz
Frequency stepsiz: 1.011 MHz
Frequency tolerance: 5.000 MHz
Symbol rate (min): 1.000000 MSym/s
Symbol rate (max): 45.000000 MSym/s
Symbol rate tolerance: 0 ppm
Notifier delay: 0 ms
Frontend capabilities:
auto inversion
FEC 1/2
FEC 2/3
FEC 3/4
FEC 4/5
FEC 5/6
FEC 6/7
FEC 7/8
FEC AUTO
QPSK
Current parameters:
Error(95): frontend ioctl: Operation not supported

That means the DVB-S2 frontend is not recognized... only DVB-S, but this is
my frontend (/dev/dvb/adapter0/frontend0) :

sorry about the structure of the text...

So I don't understand why my frontend doesn't recognized DVB-S2...
If anyone have an idea????

Thanks,
