Following devices might need firmware.tgz (if analogue doesn't work out try firmware_v2.tgz or firmware_v3.tgz and please report it to me (mrechberger at gmail.com) it's very likely that some of these devices require firmware_v3 to get audio work ):

* Terratec Cinergy Hybrid T XS (french edition)
* Terratec Cinergy T XS
* DNT DA2 Hybrid
* Kworld 350U

cd /lib/firmware 
sudo wget http://konstantin.filtschew.de/v4l-firmware/firmware.tgz 
sudo tar xvzf firmware.tgz

These devices require firmware v2:

* MSI DigiVox A/D
* Kworld 310U
* Terratec Cinergy Hybrid T XS (USB ID=0ccd:005e)

cd /lib/firmware 
sudo wget http://konstantin.filtschew.de/v4l-firmware/firmware_v2.tgz
sudo tar xvzf firmware_v2.tgz

These devices require firmware v3:

• HVR 900 B2C0(sticker on the dev.)
• HVR 900 A1C0
• Terratec Cinergy Hybrid T XS
• Pinnacle PCTV Hybrid Pro
• Pinnacle PCTV Hybrid Pro Stick (320e) (USB ID=eb1a:2881)

cd /lib/firmware
sudo wget http://konstantin.filtschew.de/v4l-firmware/firmware_v3.tgz
sudo tar xvzf firmware_v3.tgz

These devices require firmware v4:

* Pinnacle HD Pro Stick (North American version, NTSC/ATSC)

cd /lib/firmware
sudo wget http://konstantin.filtschew.de/v4l-firmware/firmware_v4.tgz
sudo tar xvzf firmware_v4.tgz

The firmware is a piece of software which is needed by your device and gets uploaded by the linux driver, it's not stored on the device itself so you won't change the behaviour of that device in windows.

• Requirements: Hg from http://www.selenic.com/mercurial/ (for ubuntu (and debian): sudo apt-get install mercurial)
• the linux kernel sources for your kernel, 2.6.15+ Kernels are well tested, everything below might cause problems with the usbaudio support (for ubuntu (and debian): sudo apt-get install kernel-source-2.6.15 kernel-headers)
• check out the sourcecode (do not use the webfrontend for downloading the repository):

Stable:

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

if this repository is down you can try my mirror

 hg clone http://linuxtv.org/hg/~mrechberger/v4l-dvb-kernel

(thanks to Nima Paknejad for providing the webspace and the domain)

• build the source (commands are prefixed with #, the second # in a line is usually a comment):

 #  cd v4l-dvb-kernel
 # make
 now as root:
 # make install
-- before posting any error messages, reboot your machine here  --
now load the drivers (as root):
 # modprobe em28xx

To verify that your setup was correct you might compare your dmesg output with ones on following wiki site: dmesg If you device isn't listed there please help to complete the list and add your device there too.

scanning for channels for xine (dvbscan is called scan in debian)

$ dvbscan -n -o zap -p de-Muenchen > ~/.xine/channels.conf #replace de-Muenchen with your frequencyfile
# for ubuntu 6.06 (and maybe others?) try something like this:
# scan -n -o zap -p /usr/share/doc/dvb-utils/examples/scan/dvb-t/de-Koeln-Bonn # replace de-Koeln-Bonn with your frequencyfile
>>> tune to: 754000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_1_2:FEC_NONE:QAM_16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE
0x0000 0x0022: pmt_pid 0x0220 BR -- Bayerisches FS (running)
0x0000 0x0023: pmt_pid 0x0230 BR -- BR-alpha (running)
0x0000 0x00e1: pmt_pid 0x0e10 BR -- SÜDWEST BW (running)
0x0000 0x0041: pmt_pid 0x0410 BR -- hr-fernsehen (running)

I'll add support for other applications by time when I have DVB-T around again. But for now only dvbscan, xine and kaffeine are well tested and supported.

If you have any problems with the installation have a look at http://mcentral.de/wiki/index.php/Talk:Em2880 this site contains some frequently asked questions, you're invited to extend that site!
