Making it Work

Make sure that the external power supply is connected!!!

Experimental driver (recommended)

The experimental merge of the original driver with the v4l-dvb project is capable of using both tuners.

$ git clone git://projects.vdr-developer.org/mediapointer-dvb-s2.git
$ cd mediapointer-dvb-s2
$ make menuconfig
  --> Multimedia support
    --> Video capture adapters
      <M> Micronas nGene support      --> <M> selektieren, wenn nicht schon vorhanden
$ make
$ sudo make install
$ sudo depmod -ae      --> zur Sicherheit
$ sudo modprobe ngene

Original driver

"To install the driver you need a Linux kernel 2.6.19 or higher. Other kernel versions might also work but are currently not tested." (see ngene/README)

The current implementation is only capable of using one tuner and doesn't support the S2API.

$ wget http://www.media-pointer.de/WebRoot/Store21/Shops/62290022/4AB0/D7EA/2E65/766B/4B4E/C0A8/28BE/FE04/ngene.tgz
$ tar xzf ngene.tgz 
$ cd ngene

Delete or uncomment line 57 and 59 in file ngene.c to ensure that variable adapter_nr will be set.

 //#if LINUX_VERSION_CODE > KERNEL_VERSION(2,6,28)
 DVB_DEFINE_MOD_OPT_ADAPTER_NR(adapter_nr);
 //#endif

$ make install
$ modprobe dvb_ngene
