The TerraTec T6 is a dual DVB-T USB-device. The device is supported by the kernel, but requires additional proprietary firmware to be loaded to function.

This tutorial was tested for a Terratec T6 with the Afatech AF9035 chipset. There is a package in the AUR, but it does not work at this time.

## Identify chipset

Filter dmesg to find out the exact chipset with the following command:

    # dmesg | grep dvb

    usb 3-1: dvb_usb_af9035: prechip_version_00 chip_version_03 chip_type_3802
    usb 3-1: dvb_usb_af9035: prechip_version=00 chip_version=03 chip_type=3802
    usb 3-1: dvb_usb_v2: found a 'Afatech AF9035 reference design' in cold state

The cold state indicates it is not active, due to the missing firmware file.

## Install firmware

The firmware was made available at dvb-usb-af9035-fwAUR

After installing the package and re-plugging the device, dmesg should show the firmware loaded and the device is now in warm state:

    # dmesg | grep -e dvb -e af9033

    usb 3-1: dvb_usb_af9035: prechip_version=00 chip_version=03 chip_type=3802
    usb 3-1: dvb_usb_v2: found a 'Afatech AF9035 reference design' in cold state
    usb 3-1: dvb_usb_v2: downloading firmware from file 'dvb-usb-af9035-02.fw'
    usb 3-1: dvb_usb_af9035: firmware version=12.13.15.0
    usb 3-1: dvb_usb_v2: found a 'Afatech AF9035 reference design' in warm state
    usb 3-1: dvb_usb_v2: will pass the complete MPEG2 transport stream to the software demuxer
