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.
In kernels 4.10 - 5.1 the driver has an issue that causes the device to hang at some point when tuning.
