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
