Good day to Everyone.

I have a problem with the TT S-1401 card. It seems, it cannot talk to diseqc
switch correctly under Linux. I am sure the problem is local to Linux code, for
i have it working in XP.

I have the card connected to LNB0: Eutelsat-21.5E and LNB1:Hotbird. 
Scanning of LNB0:
# scan -s 0 Eutelsat-21.5E
is successful.

When I try to scan Hotbird, i get
# scan -s 1 Hotburd-13.0E 
scanning Hotburd-13.0E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12597000 V 27500000 3
>>> tune to: 12597:v:1:27500
WARNING: >>> tuning failed!!!
>>> tune to: 12597:v:1:27500 (tuning failed)
WARNING: >>> tuning failed!!!
ERROR: initial tuning failed
dumping lists (0 services)

I am sure that the signal from HB is OK, because i tried to scan it while
connected directly (w/o diseqc), and it was all right.

I have Mercurial drivers 15d2ed3a6af2 installed. 

My dmesg:
