Making it Work

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

Firmware

$ wget http://www.digitaldevices.de/download/ngene_15.fw
$ cp ngene_15.fw /lib/firmware/

Driver

$ hg clone http://linuxtv.org/hg/v4l-dvb/
$ cd v4l-dvb
$ make
$ make install

Note (2010-03-09): v4l-dvb Requires at least kernel 2.6.31

Note (2010-08-26): kernel 2.6.34/35 (maybe 2.6.33 too) has a driver (CONFIG_DVB_NGENE=m) included. Haven't tried yet since my mainboard is dead currently but it looks like that building it manually isn't needed any more.

Multiple Frontends

This device shows as one adapter with multiple frontends. If you want to use software that doesn't support it you can create symlinks. I use the following UDEV rule to ensure that each card keeps the same device number, and each frontend appears as its own adapter:

 /etc/udev/rules.d/10-persistent-dvb.rules
 
 SUBSYSTEM=="dvb", ATTRS{device}=="0x0374", PROGRAM="/bin/sh -c ' K=%k; K=$${K#dvb}; A=$(echo -n $K | tail -c -1); A=$(echo 100+$A | bc); N=$${K#*.}; N=$(echo -n $N | head -c -1); printf dvb/adapter%%s/%%s0 $A $N; exit 0'", SYMLINK+="%c"
 SUBSYSTEM=="dvb", ATTRS{device}=="0x0376", PROGRAM="/bin/sh -c ' K=%k; K=$${K#dvb}; A=$(echo -n $K | tail -c -1); A=$(echo 102+$A | bc); N=$${K#*.}; N=$(echo -n $N | head -c -1); printf dvb/adapter%%s/%%s0 $A $N; exit 0'", SYMLINK+="%c"
 SUBSYSTEM=="dvb", ATTRS{device}=="0x0377", PROGRAM="/bin/sh -c ' K=%k; K=$${K#dvb}; A=$(echo -n $K | tail -c -1); A=$(echo 104+$A | bc); N=$${K#*.}; N=$(echo -n $N | head -c -1); printf dvb/adapter%%s/%%s0 $A $N; exit 0'", SYMLINK+="%c"

The ATTRS{device}=="0x0374" part is the unique identifier of the slot the card is plugged into. The cards cannot be identified uniquely from each other as I have 3 identical cards. The 100, 102, and 104 are the adapter numbers I am using for each card, the +$A adds the frontend number so that the two frontends will appear as adapters 100 and 101.

Another way for create multiple adapter:

The option "one_adapter" in module ngene create one or two apdater.

For ubuntu, create one file in "/etc/modprobe.d/dvb.conf" and add "options ngene one_adapter=0" or "options ngene one_adapter=1".

For one adapter:

options ngene one_adapter=1

For two adapter:

options ngene one_adapter=0
