The firmware for the tuner is the same as for TechnoTrend TT-TVStick CT2-4400#Firmware
The demodulator needs a firmware that can be extracted from the Windows drivers. File ttConnect4650_64.sys should be extracted from the driver package (MD5 sum below).
Then the firmware can be extracted:
dd if=ttConnect4650_64.sys ibs=1 skip=273376 count=6424 of=dvb-demod-si2168-a20-01.fw
IR Remote Control
The supplied remote control is supported by the driver.
