TerraTec T6 DVB-T (Afatech AF9035)
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.
Download firmware
The firmware file in this case was made available at: [1]
Download the file of your choice and navigate to the download-folder.
Install firmware
Without a PKGBUILD the file cannot be installed (and tracked) with pacman. However, for a firmware the main step of an installation is to move the file into the /lib/firmware path.
If you move the file manually and re-plug the device, dmesg should show the firmware loaded and the device is now in warm state:
