TechnoTrend TT-connect S2-3650 CI
A DVB-S2 USB 2.0 Device from TechnoTrend. Identical to the TechnoTrend TT-connect S2-3600, but bundled with a CI interface.
It is currently unsupported, but experimental support has been attempted.
Overview/Features
This is a USB 2.0 device capable of receiving DVB-S and DVB-S2 tranponders.
Upon connection to the USB port, the devices' LED is orange and turns green upon module load.
The USB receiver comes with a black RC5 remote control. IR events can be read from /dev/input/eventX
Components Used
- Cypress CY7C68013A USB controller [1]
- STM STB0899 (demodulator) [2]
- STM STB6100 (tuner) [3]
- STM LNBP22 (LNB voltage regulator) [4]
- STM M24C64 (EEPROM containing USB controller firmware, MAC address) [5]
Identification
Vendor ID: 0B48
Product ID: 300A
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 - ttpci-eeprom.ko - dvb-usb.ko - dvb-usb-pctv452e.ko
To use this device you have to have a tuning application that uses the new S2API or multiproto 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:
S2API
(at least for S2API there is no patch required anymore (july 2009), not tested: HDTV and Remote Control, tested and running: SDTV, CI with Alphacrypt CAM)

Driver Status
Working:
- Remote Control - LNB Power (13/18V) - 22kHz - DiSEqC - DVB-S - DVB-S2 - Common Interface
A problem with locking high symbol rate channels (DVB-S2 30000 3/4 transponders) has been reported a number
of times for the similar (but PCI not USB) TechnoTrend TT-budget S2-3200, but has not been solved.

http://linuxtv.org/pipermail/linux-dvb/2009-February/031779.html .
This problem also exists for the TT S2-3650 CI USB.
Such transponders can be found at Thor 0.8W and Hispasat 30.0W.
A way to use the similar (but USB) TechnoTrend TT-connect S2-3650 CI to help fix problem has been suggested here: http://www.spinics.net/lists/linux-media/msg01169.html .
Do you have the TT S2-3200 or TT S2-3650 ? Can you help debug the driver?
