Artec T1 USB TV Box

A DVB-T USB device from Artec.

It is supported under Linux.

Overview/Features

The device is based upon the DiBcom DVB-T USB 1.1 reference design.

There are several clones of this device: some have the AN2235 USB controller instead of the AN2135; some use a Panasonic tuner instead of the default Thomson Cable tuner. Most of the Boxes have standard Cypress USB IDs which makes it very hard to identify them.

Components Used

Making it work

Firmware

You will need either the dvb-usb-dibusb-5.0.0.11.fw or dvb-usb-dibusb-an2235-01.fw firmware file in /lib/firmware (or the relevant place for your distribution).

Drivers

Just use the in-kernel drivers, or compile your own by following the How to Obtain, Build and Install V4L-DVB Device Drivers instructions.

You may need to make sure that the "Support faulty USB IDs" option is enabled.
