	Capabilities: <access denied>
	Kernel driver in use: ngene
	Kernel modules: ngene

Making it Work

"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.

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

$ 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

Until now no support by http://linuxtv.org is given.
