I wanted a DVB-T USB stick (which I will probably want to plug in DSM-G600 and have network TV in later phase) with ability to receive both analog and DVB-T signal, so I bought Hauppauge HVR 900 while my UK visit.

$ lsusb | grep Hauppauge
Bus 005 Device 004: ID 2040:6502 Hauppauge

Following instructions are slight modification of blog post in German which I used with a bit of Google translate to make it work on Debian unstable. I will assume that you already have kernel source and build tools, because you are running unstable :-)

• dmesg output after plugging in the card: Hauppage_WinTV_HVR_Rev._1.2.dmesg
• upstream driver

This instructions are based on spanish ones with updated urls

Fetch drivers

mkdir hvr900
cd hvr900/
wget 'http://supportde.terratec.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=1049'
unzip Cinergy_T_USB_XE_Drv_Vista_XP_6.11.23.01.exe
cp Cinergy\ T\ USB\ XE/BDA\ Driver\ 6.11.23.01/Windows\ Vista\ \(32Bit\)/AF05BDA.sys .

Install development tools

udo apt-get install mercurial make gcc libc6-dev kaffeine

Checkout latest source

hg clone http://mcentral.de/hg/~mrec/v4l-dvb-experimental

Extract firmware

cd v4l_experimental/xc3028/
gcc -o convert convert.c

Alternative approach from mailing list

hg clone http://mcentral.de/hg/~mrec/userspace-tuner/
cd userspace-tuner
sudo ./build.sh
cd .
.
hg clone http://mcentral.de/hg/~mrec/em28xx-userspace2/
cd em28xx-userspace2
make
modprobe em28xx.ko // this will load the videodev modules
rmmod em28xx.ko
insmod em28xx.ko
