KWorld UB499-2T T09	✔ Yes, in kernel since 3.2	1b80:e409 USB2.0	IT9137	dvb-usb-it9137-01.fw

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 so for those who do not speak dutch I will add instructions below. Until then you can use any online translation page to get an idea how to install.

I have tested the driver on Mythbuntu 10.04 with kerner version 2.6.32 and it appears to function perfectly.

Many thanks to wasietsmet.nl for this solution and Axel for finding it.

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.
