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


  • 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.

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.


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


Available here. Look for the TBS5980 driver. Latest update: july 10. Apart from the firmware file, there is no closed-source object code included in the software. All code has been released under GPLv2.

Sample Kernel Output

The kernel outputs the information below, CAM module inserted (with module verbosity wide open):

To get maximum verbosity, relevant parts of /etc/modprobe.d/modprobe.conf were set as follows:

options dvb_usb debug=511
options dvb_usb_tbsqbox2ci debug=3
options stb6100 verbose=3

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.

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.
