A DVB-S2 USB 2.0 Device from Pinnacle.

It is currently unsupported, but is identical to the TechnoTrend TT-connect S2-3600 which has experimental support via patches.


Evidently, as can be seen in the images, the silkscreen writing on the PCB indicate that this device is actually a [TechnoTrend] design, identical to the S2-3600.

Components Used


It has a USB ID: 2304:021f

Making it Work

What we know:

  • it uses parts/all of the ttusb-USB-protocol
  • isochronous Data transfer (whole TS only)
  • no firmware is needed (budget device)


Here's a step by step howto for Linux 2.6.x:

hg clone
cd s2-liplianin
# you might have to edit v4l/.config and disable CONFIG_DVB_FIREDTV
make install

For Linux 3.x kernels you can use the media build of linuxtv:

git clone git:// 
cd media_build 
make install

Since Linux 3.2 the driver is included in the standard kernel. You do not need any additional driver.

Driver Status


- Remote Control
- LNB Power (13/18V)
- 22kHz
- DiSEqC
