Overview/Features

This is technically a very interesting card. According to this mailing list post, the hardware is as follows:

Support

This card is now supported since kernel v3.9-rc1

Under Windows it performs well, however the two software programs provided are not intuitive, and are not as good as gbtv which also supports this card.

For Linux support:
It was reported in early 2006 that TerraTec were working on a Linux driver, with the first beta version expected to have been released in week 12. However, later inquiries to TerraTec (circa 29-5-06) in regards to the status of their driver development were met with responses that no Linux drivers were being developed! In a strange twist, it has now (June 2007) come to light that someone at TerraTec did indeed develop some drivers for this card back in April 2006 (see this mailing list post for details).

It would be nice if LinuxTV could provide its own drivers, but there are several roadblocks in the way. If you are eager to aide such development, then it might be helpful to send an email to TerraTec (briefkasten@terratec.de) and ask them to release any information they can to assist others to write drivers.

Update: it is possible to make this card work under Linux - see NGene_devices

Update2: Here's a forum post with a driver for download (in the excellent German Ubutuusers-forum) which appears to work as of 18th Dec 2010.

And a decription of installing the Card in the German Wiki of above website.

Firmware

Although now supported under modern kernels, some linux distributions (for instance Fedora) may need to install firmware to get this card working.

The drivers will have installed correctly from the kernel if the card is listed using when you type "lspci". If the card is nevertheless not working,

double check you have the drivers by typing:

lsmod ¦ grep ngene

Check driver status:

dmesg ¦ grep ngene

If your output says something like:

[ 3.757422] ngene: Found Terratec Integra/Cinergy2400i Dual DVB-T

[ 3.758052] ngene: Device version 1

[ 3.759422] ngene: Could not load firmware file ngene_15.fw.

[ 3.759424] ngene: Copy ngene_15.fw to your hotplug directory!

[ 3.759489] ngene: probe of 0000:02:00.0 failed with error -1

You can find the appropriate firmware, with instructions, on this page: [1]

Update: It also turns out the MICRONAS DRX 3975D demodulator needs firmware. If you are having trouble tuning the card, install this with:

wget http://kernellabs.com/firmware/drxd/drxd-a2-1.1.fw sudo cp drxd-a2-1.1.fw /lib/firmware
