The KWorld UB499-2T is a USB dual tuner. It contains the Afatech/ITE IT9135 hardware. It is not supported directly by V4L, however, a driver is available along with instructions for installation from http://wasietsmet.nl/linux/zolid-usb-dvb-t-tuner-van-de-aldi-linux-drivers/. This page is in Dutch, however English installation instructions for Ubuntu are provided below.

I have tested the driver on Mythbuntu 10.04 with kerner version 2.6.32. The dual tunar appears to function perfectly, however, I have not made any attept to get the included IR receiver and remote working.

The IT9137 version (packaged as KWorld UB499-2T) tested and both tuners working with the 9135 driver above with Mythtv 0.23 on Ubuntu 10.04 kernel 2.6.32-24-generic.

Installation Instructions

These instructions have been written after my work colleague Axel pointed me to the Dutch page http://wasietsmet.nl/linux/zolid-usb-dvb-t-tuner-van-de-aldi-linux-drivers/ which contains a link to the drivers and installation instructions in Dutch. Although it is relatively easy to translate the page using an online translator I thought it sensible to add a section here in the v4l wiki in English for completeness.

Again thanks to those mentioned above.

If you don't allready have them install linux headers for your kernel and gcc

 sudo apt-get install linux-headers-$(uname -r) gcc

Create a folder for the source code (for example in your Documents folder) and cd into it.

 mkdir IT9135_SRC_i686_patch
 cd IT9135_SRC_i686_patch

Download the driver source code from http://wasietsmet.nl/wp-content/uploads/2010/07/IT9135_SRC_i686_patch.tar.gz to your new folder either using your browser or using

 wget http://wasietsmet.nl/wp-content/uploads/2010/07/IT9135_SRC_i686_patch.tar.gz

Unpack the sourcecode and run the install script. Follow the onscreen instructions entering option 1 to install the module

 tar xvzf IT9135_SRC_i686_patch.tar.gz
 ./installer.sh

Load the module

 sudo modprobe dvb-usb-it9135

Test the tuner is working by scanning for channels. First find the correct file for your transmitter then scan. The example below lists all files for uk transmitters then uses uk-EmleyMoor. Modify the ls command to list all transmitters or those in your country and replace uk-EmleyMoor with the file for the transmitter you use. If the scan succeeds you have successfully installed the tuner.

 ls /usr/share/dvb/dvb-t | grep uk-
 scan /usr/share/dvb/dvb-t/uk-EmleyMoor

Ensure that the module is loaded on reboot by adding it to your /etc/modules file using your favourite text editor, eg to use nano

 sudo nano /etc/modules

then add the line

 dvb-usb-it9135

to the file.

Supporting Newer Kernels

The driver linked above only supports kernels up to 2.6.33. For newer kernels please follow the instructions below.

Updating for the 2.6.34 & 2.6.35 kernels

just use the new driver that was recently posted on the same dutch forum (http://wasietsmet.nl/linux/zolid-usb-dvb-t-tuner-van-de-aldi-linux-drivers/)

http://wasietsmet.nl/wp-content/uploads/2010/07/V10.12.30.1.zip

just read the read me in the file and follow it's instructions.

Note: I could not make this driver (10.12.30.1) or the old one (10.04.19.1) work in Fedora 14. Fedora 14 uses kernel 2.6.35. I had to upgrade the kernel to 2.6.37 and it worked following the procedures described below for kernel 2.6.37, but I had to use version 10.12.30.1, the earlier version (10.04.19.1) didn't work for me on kernel 2.6.37.

Updating for the 2.6.36 & 2.6.37 kernel

I have created two 10.12.30.1 versions (i686 and x64) that work with kernel 2.6.37 following the procedure below.

You can download them here:

http://www.omcentre.com.au/fileadmin/user_upload/kworld_UB499-2T/IT9135-10.12.30.1_i686.tar.bz2

http://www.omcentre.com.au/fileadmin/user_upload/kworld_UB499-2T/IT9135-10.12.30.1_x64.tar.bz2

To install the i686 as root:

wget http://www.omcentre.com.au/fileadmin/user_upload/kworld_UB499-2T/IT9135-10.12.30.1_i686.tar.bz2
tar xvfj IT9135-10.12.30.1_i686.tar.bz2
cd IT9135_SRC
make
make install

To install the x64 one follow the same procedure replacing i686 with x64.

The 2.6.36 kernel introduced a big change towards removing the Big Kernel Lock, which was finally removed in 2.6.37. As a result the module mentioned above wouldn't build.

At the bottom of the Cellie's post there is a link to an updated source package that is supposed to work with the 2.6.36 kernel, however I wasn't able to make this work. The Release Notes indicate an updated firmware in that package, but a cmp between the firmware in the initially posted v10.04.19.1 and the updated v10.12.30.1 for x86 & amd64 appear to be identical. The notes also indicate better support for PIP so I'd like to get this going at some point.

I'm no C programmer, and much less a kernel hacker, but I found enough info to be able to patch the v10.04.19.1 module to build and fully function on these kernels. The following patch includes the necessary ioctl change for kernels >= 2.6.36, along with the other changes for kernels > 2.6.33.

To use the patch

  • Enter the unpacked source folder for the IT9135_SRC_i686_patch.tar.gz package
  • Save the following patch to patch_file
  • Use "patch -p0 < patch_file" to apply the changes to the source
  • Run the helper script below to populate the necessary sources from the kernel tree
  • Use the installer as instructed in the source to build & install the module
