A DVB-S2 USB 2.0 Device from Pinnacle.

It is currently unsupported.

Overview/Features

Evidently, as can be seen in the images, the silkscreen writting on the PCB indicate that this device is actually a TechnoTrend design.

Components Used

  • STM STB6100 (tuner) [1]
  • STM STB0899 (demodulator) [2]
  • Cypress CY7C68013A (i.e. FX2) (USB bridge/controller) [3]

Identification

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)

Drivers

The following drivers are needed for these devices: 

 - stb0899.ko
 - stb6100.ko
 - lnbp22.ko
 - dvb-usb.ko
 - dvb-usb-pctv452e.ko

To use this device you have to have a tuning application that uses the new DVB api. there's a patched version of szap available (search mailing list).

Make sure you haven't loaded any old dvb drivers. Here's a step by step howto:
