Making it Work

Firmware

Supplied by manufacturer (v 1.22.82.0)

Prof supplies a zip file which contains the firmware file dvb-fe-cx24116.fw which is version 1.22.82.0.

Copy this file to /lib/firmware and reboot your computer or reload the driver modules.

Supplied by TeVii (v 1.23.86.1)

Firmware v1.23.86.1 is available with the TeVii S460 Linux driver at http://tevii.com/Support.asp.

wget http://tevii.com/Tevii_linuxdriver_0815.rar
sudo apt-get install unrar-free
unrar x Tevii_linuxdriver_0815.rar
sudo cp tevii_linuxdriver_0815/fw/dvb-fe-cx24116.fw /lib/firmware/dvb-fe-cx24116-1.23.86.1.fw
sudo ln -s /lib/firmware/dvb-fe-cx24116-1.23.86.1.fw /lib/firmware/dvb-fe-cx24116.fw

You can also have a look at Hauppauge_WinTV-HVR-4000#Firmware. It uses the same firmware.

Firmware loading

On first usage, read or tuning, of the driver the module CX24116 will try to load a firmware file called dvb-fe-cx24116.fw which must exist in /lib/firmware. For instructions see Firmware section.

On succesfull load you will see the following message in your kernel log (Example in dmesg this if for fw version 1.22.82.0)

#> dmesg | grep -i firmware
cx24116_firmware_ondemand: Waiting for firmware upload (dvb-fe-cx24116.fw)...
firmware: requesting dvb-fe-cx24116.fw
cx24116_firmware_ondemand: Waiting for firmware upload(2)...
cx24116_load_firmware: FW version 1.22.82.0
cx24116_firmware_ondemand: Firmware upload complete
