The Qbox DVB-S2 CI USB2.0, as the name suggests, is a DVB-S2 USB 2.0 adapter from TurboSight. It has been on the market since early 2011. The company has no distribution network, but their products can be ordered online. Shipping of my device to Western Europe took less than three days.

The Qbox DVB-S2 CI is supported under Linux. The minimum required kernel version is (yet) unknown, the driver requires DVB version 5.1.

The Qbox CI switched on. The CAM module has not been inserted

Overview/Features

  • USB 2.0 interface (B-connector)
  • Inputs: Antenna (F-connector), remote and CI-slot
  • Separate power supply: 7.5V, 3.5A
  • Indication LED, mostly red, sometimes blue, meaning yet unknown.
  • CCM mode support ONLY (NO support for VCM and ACM modes used by a lot of DVB-S2 multistream Free TV channels with Eutelsat 5 West A (5°W) satellite)

Making it Work

The device is actively supported to run under Linux. Every few months the driver gets updated, and the company actively supports users through a forum. By downloading, compiling and installing the drivers and firmware, the device works (at least, in my distro, Fedora 14 x86-64). Together with the manufacturer-supplied source code for scanning and zapping (slightly modified versions of scan-s2 and szap-s2) DVB-S2 reception works. Newer versions of szap and scan work just as well.

Firmware

The driver software package contains the firmware file: dvb-usb-tbsqbox-id5980.fw. Just install it in /lib/firmware.

Drivers

For linux with x86 or X86-64 CPU

Available here from TBS website. Look for the TBS5980 driver. Latest update: 29/12/2015. Apart from the firmware file, there is no closed-source object code included in the software. All code has been released under GPLv2.

For compiling and installing the Open-source drivers or the Closed-source drivers, see TBS driver installation.

For Linux with ARM CPU in Raspberry PI

WARNING : THIS INSTALLATION PROCESS IS A DRAFT, IT IS NOT FINISH YET. THIS WARNING MESSAGE WILL BE REMOVE WHEN THE INSTALLATION PROCESS WILL BE FULL

The open source driver is available here. Some instructions above are taken from http://www.satelliteguys.us/xen/threads/hobbyist-open-source-satellite-receiver-raspberry-pi-2-instructions-and-tips.348466/#post-3652518 but a lot of steps for installing and compiling are missing from this link.

You mustn't use the remote control because it use a lot of of CPU power.

Building the Open Source Driver

These instructions are taken from satelliteguys.us forum and Raspberry PI official website:

Compilation and Installation process with :
-Hardware : Raspberry Pi 2
-Operating System : Raspbian in NOOBS Version 1.9.1 Full and with the Release date: 2016-05-10

  • Check your Linux kernel release :
uname -r
  4.4.9-v7+

Note the major and minor kernel release number, here 4.4.

  • Update the package list available in distro repositories and then update the package installed on your system :
sudo apt-get update
sudo apt-get upgrade
  • Install the packages required to compile the TBS driver for Raspberry PI in his ARM CPU :
sudo apt-get install patchutils
sudo apt-get install bc
sudo apt-get install libncurses5-dev
sudo apt-get install git
sudo cpan Proc::processTable
 CPAN.pm requires configuration, but most of it can be done automatically.
 If you answer 'no' below, you will enter an interactive dialog for each
 configuration option instead.
 Would you like to configure as much as possible automatically? [yes] yes
  • Get the Linux kernel sources for Raspbian and then next the open source TBS driver

Note you must get the kernel sources for raspberry pi with the same release number than the release number in the output of the previously used uname command, here 4.4 for the file rpi-4.4.y.tar.gz. 

sudo su - root
ls /etc/modprobe.d/
  fbdev-blacklist.conf  ipv6.conf  libpisock9.conf  raspi-blacklist.conf
cd /usr/src
wget https://github.com/raspberrypi/linux/archive/rpi-4.4.y.tar.gz
tar xzvf rpi-4.4.y.tar.gz
ls /usr/src/linux-rpi-4.4.y
cd /root
git clone --depth=1 https://github.com/ljalves/linux_media.git -b latest ./media
  • Copy driver sources into kernel source directories

Note : As of 6/6/2016, the following files below are the same in /root/media/drivers/ and /usr/src/linux-rpi-4.4.y/drivers folders, except for stv090x.c, stv090x.h . These files in /root/media/drivers/ are patched and have an adding for lock led hooks to the stv090x, stv0288, cx24116 and tda10071 frontends. Similar code already exists in the stv0900 frontend. source code patch.
For the file technisat-usb2.c, the line .count = 4 are replaced by .count = 8.
Note 2 : As of 6/6/2016, tbs-qbox2ci.c and tbs-qbox2ci.h files, for the TBS 5980 driver, are only available in /root/media/drivers/ from https://github.com/ljalves/linux_media.git repositories.

Remote Control Support

The device comes with a remote, but that has not been tested yet. Tbsdtv forum members complain about poor interoperability with LIRC.

Issues

Remote control needs further research.

CAM support is underway. So far, the astoncrypt v1.07 has been tested. Before this can be finalized, a working smartcard is required. Haven't got one yet ;-).

Network support has not been addressed yet.
