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/linux_tevii_ds3000.rar
unrar x linux_tevii_ds3000.rar
cp dvb-fe-cx24116.fw /lib/firmware/dvb-fe-cx24116-1.23.86.1.fw
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.

Reportedly supported.

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. Because of this upload the first tuning will take a bit longer beacuse it is waiting for the firmware upload.

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
