---------------------------------------------------------------------------
KNOWN PROBLEMS:
about preemphasis:
You can set the preemphasis for radio by the following command:
#v4l2-ctl -d /dev/radio0 --set-ctrl=pre_emphasis_settings=1

"pre_emphasis_settings=1" means that you select the 50us. If you want
to select the 75us, please use "pre_emphasis_settings=2"


country code
- The firmware of the chip needs the country code to determine
the stardards of video and audio when it runs for analog TV or radio.
The DVB-T does not need the country code.

So you must set the country-code correctly. The V4L2 does not have
the interface,the driver has to provide a parameter `country_code'.

You could set the coutry code in two ways, take USA as example
(The USA's country code is 1):

[1] add the following line in /etc/modprobe.conf before you insert the
card into USB hub's port :
poseidon country_code=1

[2] You can also modify the parameter at runtime (before you run the
application such as VLC)
#echo 1 > /sys/module/poseidon/parameter/country_code
