[linux-dvb] Need Help with PCTV 452e (USB DVB-S2 device with STB0899)

["Jens Krehbiel-Gräther" <linux-dvb@okg-computer.de>]

Hi!

After two defective devices I got now a working one from pinnacle 
support (I tested it in Windows and it works fine).

But under Linux I could not get a positive scan or channel-lock. Could 
please anyone tell me what I am doing wrong? I read the list and 
searched the list archive and did everything described here, but my 
device isn't working.

I followed the instructions of the wiki about this device:

hg clone http://www.jusst.de/hg/multiproto
wget -O pctv452e.patch http://www.linuxtv.org/pipermail/linux-dvb/attachments/20080125/b9e1d749/attachment-0001.patch
cd multiproto
patch -p1 < ../pctv452e.patch
make ; # there might be a few warnings.
cd v4l
insmod dvb-core.ko
insmod dvb-pll.ko
insmod stb6100.ko verbose=0
insmod stb0899.ko verbose=0
insmod lnbp22.ko
insmod dvb-usb.ko
insmod dvb-usb-pctv452e.ko
# in case some insmod complains about unresolved symbols: 
modprobe firmware_class


I can compile multiproto and install the modules. The device ist 
recognized when plugged in:

syslog tells this:

I downloaded the dvb-apps:
hg clone http://linuxtv.org/hg/dvb-apps

I downloaded the patched scan:
wget http://jusst.de/manu/scan.tar.bz2

I downloaded the patched szap:
wget http://abraham.manu.googlepages.com/szap.c

I updated version.h and frontend.h in the include path with the version 
of multiproto. Everything compiles fine, but finally nothing works.

When I scan for channels, this is the output after some time:

scanning dvb-s/Astra-19.2E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12551500 V 22000000 22000000

WARNING: >>> tuning failed!!!
Tune to frequency 12551500

WARNING: >>> tuning failed!!!

Done.


In the syslog I got this entry several times:

Feb 21 17:06:15 dev kernel: _stb0899_read_reg: Reg=[0xf41b], data=ee
Feb 21 17:06:15 dev kernel: stb0899_write_regs [0xf41b]: ee

STB0899_DSTATUS=[0x08]
Feb 21 17:06:15 dev kernel: stb0899_check_carrier: -------------> 
NOCARRIER !

So what can I do to make things work? What am I doing wrong since other 
people here report successfull working devices?
I have several lines of this in the syslog:

Feb 21 17:06:56 dev kernel: lnbp22_set_voltage: 2 (18V=1 13V=0)

Is this OK or ist this an error (set_voltage 2)?? If 0=13V and 1=18V 
what is 2??

Jens
