Latest revision as of 06:08, 6 November 2013

A DVB-T USB device from Leadtek.

Overview/Features

  • Supplied with a remote control and antenna.

Components used

  • Afatech AF9035 demodulator and USB bridge
  • Dual ITE Tech IT9135 tuners

Identification

The USB ID is:

  • 0413:6a05

Driver Installation

Afatech AF9035 demodulator and USB bridge

By default the firmware driver for the Afatech AF9035 demodulator and USB bridge is not supported in the kernel and must be installed separately.

To install the driver you will need your kernel headers and other software requirements installed, as listed here

To install the firmware driver enter the following commands into a terminal:

$ su
# cd /lib/firmware/
# wget -O dvb-usb-af9035-02.fw http://palosaari.fi/linux/v4l-dvb/firmware/af9035/dvb-usbaf9035-02.fw_3735d499d945a6bb873a7f3ad5c701fa_12.13.15.0_6.20.15.0

Your TV tuner's demodulator and USB Bridge firmware driver is installed. The next step is to install the driver for the dual ITE Tech IT9135 tuners.

Dual ITE Tech IT9135 tuners

To install the tuner firmware driver, enter the following commands into a terminal:

 # cd /lib/firmware/
 # wget https://github.com/OpenELEC/dvb-firmware/raw/master/it9135/dvb-usb-it9135-01.fw

Your dual ITE Tech IT9135 tuners are installed now!

Patching V4L-DVB to support the Leadtek WinFast DTV Dongle Dual

Next, we need to obtain, patch and build the latest V4L-DVB source code to recognise the Leadtek WinFast DTV Dongle Dual. To do this, we adapt the "Basic" build Approach, following the instructions in the "README.patches" file that we obtain along with the rest of the V4L source code, via git.

First, we obtain the source code unpatched.

$ mkdir dvb-git
$ cd dvb-git
$ git clone git://linuxtv.org/media_build.git

Then, we obtain the patch by Antti Palosaari to get the device recognised. View the patch commit and paste the patch contents into a newly created "winfast-dual.patch" file, inside the "backports" directory, as below.

diff --git a/drivers/media/usb/dvb-usb-v2/af9035.c b/drivers/media/usb/dvb-usb-v2/af9035.c

};
MODULE_DEVICE_TABLE(usb, af9035_id_table);

Save the file.

We need to also edit "backports.txt" as instructed by the "README.patches" file, so that the build script knows to apply the patch.

The backports.txt file should be modified to included an entry, like so:

[YOUR KERNEL VERSION GOES HERE - FIND IT WITH THE "uname -r" COMMAND] 
add winfast_dual.patch # Winfast Dual Dongle patch

Once the file is edited and saved, from within the "dvb-git" folder. Execute the command

$ ./build

This will begin building the firmware drivers (if all is as it should be - with the patch included). Watch the terminal output to ensure the af9035.c file is patched correctly, before going any further. If the version number or the name of the .patch file is wrong in the backports.txt file, it won't apply.

To install the compiled patched firmware drivers, execute:

$ sudo make install
Note: If your system uses compressed kernel modules, after running the "make install" command of the V4L-DVB installation process, you could end up with a mixture of new modules (*.ko) and their older compressed version (*.ko.gz) installed. If the system attempts to concurrently load both sets into memory, you are bound to run into modprobe insertion errors (eg. unknown symbol or unknown parameter). All conflicting *.ko.gz files must be removed. The following command line can help you locate/remove these conflicting files in all your installed kernels:
$ for file in `find /lib/modules -name "*.ko"`; do if  -e $file.gz ; then echo "$file.gz should be removed"; fi; done

If you're happy to automate the removal proccess of any detected conflicting modules, run the following command at your own risk:

$ su
# for file in `find /lib/modules -name "*.ko"`; do if  -e $file.gz ; then rm "$file.gz"; fi; done

Verifying the driver installation

Once that's done, restart your computer. Once it reboots check the output of the "dmesg" command. "The Leadtek WinFast DTV Dongle Dual" should be recognised and initialised successfully. During testing, a final restart was required to get MythTV to use the tuner once it was setup in mythtv-setup.

Sample successful "dmesg" output is below:
