KWorld Dual DVB-T HD USB Stick (UB499-2T) based on Afatech AF9135

I'm using dual HD tuners in a USB stick. This is one of the few tuners that has a dual tuner inside a USB stick. It would also fit inside the tiny case so it doesn't have to be kept outside the media centre.

More information about this tuner can be found here.

Installing the KWorld Dual DVB-T HD USB Stick (UB499-2T) in Linux

Installing this double tuner in Linux was not easy. I followed the original procedures listed on http://www.linuxtv.org/wiki/index.php/Kworld_UB499-2T but they didn't work.

I have added a few entries to that page to fix the problem.

In short what I did was the following:

From this forum I downloaded this file
I tried installing from the V10.12. 30.1.zip file with original Fedora 14 kernel (2.6.35) and the driver didn't work
Then I downloaded kernel 2.6.37 for Fedora 15 and installed it in Fedora 14 (Remember to recompile Nvidia driver after installing the new kernel)
Now I'm running Fedora 15 with kernel 2.6.39
Then I realised the driver V10.12. 30.1.zip only supports kernels up to 2.6.36
I followed the indications at the bottom of the linuxtv wiki to make V10.12. 30.1 work with kernel 2.6.37, 2.6.38 and 2.6.39
After installing the driver it worked and detected the tuners

You can download a modified version V10.12. 30.1 of the driver that works up to kernel 2.6.39 here:

To install the i686 as root:

wget 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 instructions work on my old machine running Ubuntu 10.10 with kernel-2.6.37. When I try on new machine will not "make". New machine Ubuntu 11.04 with kernel-2.6.39.
Can you advise how to fix this
Thanks

I have published the updated version of the driver for kernel up to 2.6.39. Hope it helps someone.

This is really useful, thanks.

Working on ubuntu natty with kernel 2.6.38

One thing I'm noticing is that I only seem to get a single tuner. Do I need to pass some parameter to it on loading?

A reboot seems to have made it pick up the second adaptor, but I'm finding the driver very flaky so I've gone back to the Nova-T for now.

I had a lot of trouble resetting this tuner. The main problem was that the motherboard I'm using keeps the power on in the usb devices even when you shutdown the computer.
Also for whatever reason the tuner doesn't always start properly. I had to make a script to make sure that it does.
In most cases disconnecting the power of the computer or unplugging the tuner before a restart would solve the problems.

I have been using this tuner in my MythTv media centre for over a month now with no freezes. I used to have a lot of problems with my old TV antenna and the media centre would hang. From the moment I replaced my aerial with a Fracarro lp345hv everything has been working beautifully. The funny thing is that the old antenna was just an Antsig from Bunnings and costed over $100. The new one is Italian and costed $70 delivered...

Agreed. I tried compiling the driver for kernel =>3.0 but my skills are limited and it failed. Any chance of giving it a go for me?

Your last update worked well on Ubuntu 11.04 with Kernel 2.6.39. I upgraded to 11.10 and downgraded Kernel to 2.6.39,and all works ok. I have been told that Ubuntu 12.04 LTS may have some significant changes which may prevent downgrading to 2.6.39. Have you had a chance to modify the driver for 3.2?
