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.

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 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:

hg clone http://www.jusst.de/hg/multiproto
wget -O pctv452e.patch http://www.linuxtv.org/pipermail/linux-dvb/attachments/20080125/b9e1d749/attachment-0001.patch
cd multiproto
patch -p1 < ../pctv452e.patch
make ; # there might be a few warnings.
cd v4l
insmod dvb-core.ko
insmod dvb-pll.ko
insmod stb6100.ko verbose=0
insmod stb0899.ko verbose=0
insmod lnbp22.ko
insmod dvb-usb.ko
insmod dvb-usb-pctv452e.ko
# in case some insmod complains about unresolved symbols: 
modprobe firmware_class
