DVB-S/S2 USB 2.0 box from DVBSky. This device and its clone Mystique SaTix S2 V2 USB have a single LNB F-connector port, and include a IR receiver. It's supported by linuxtv as of september 2014. Support in-kernel is expected in Linux kernel 3.18.
Alternatively, compiling V4L from sources given by the producer DVBSky also allows it to run. The IR events are forwared not via LIRC but as xevents, but the shipped remote is not fully supported (e.g. the OK key does not produce a xevent).
- USB 2.0
- Low power
- Integrated IR receiver
- RF: Montage M88TS2022
- Demodulator: 2nd generation Montage M88DS3103
- USB Bridge: Cypress CY68013
Firmware and Driver
It's supported by linuxtv as of september 2014. Support in-kernel is expected in Linux kernel 3.18. If your kernel is older than 3.18, you'll have to obtain, build and install the V4L-DVB device drivers.
Alternatively you can use the drivers from DVBSky.
In kernels 4.10 - 5.1 the driver has an issue that causes the device to hang at some point when tuning.

Initialization failing with
dmesg showing something like the following:
[ 104.930775] dvbdev: DVB: registering new adapter (DVBSky S960/S860) ... [ 104.934128] m88ds3103 11-0068: Unknown device. Chip_id=00
This indicates that the device is not receiving external power. Disconnect USB, make sure the correct (12V) power adapter is properly connected, then reattach USB.
Note: The LED labeled "POWER" does not come on after power is connected, but only after USB initialization commenced. It does however not necessarily indicate that the device is operational, see below. Always make sure external power is connected before connecting USB.

In case the firmware file is missing initialization may still complete successfully. The error about the missing firmware first appears as an application tries to open the device.
