Find out what device you have
-----------------------------

Important Notice: The driver does NOT support Technisat USB 2 devices!

First start your linux box with a shipped kernel:

.. code-block:: none

	lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for example:
	02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip /
	Technisat SkyStar2 DVB card (rev 02)

	dmesg | grep frontend may show you for example:
	DVB: registering frontend 0 (Conexant CX24123/CX24109)...

Kernel compilation:

If the Flexcop / Technisat is the only DVB / TV / Radio device in your box
get rid of unnecessary modules and check this one:
