RPi: Mediaclient doesn't see stick, but okay in lsusb and dmesg

[idefixx2]

Hi,
on my RPi2 (Raspbian) the stick is shown successfully in lsusb:
> Bus 001 Device 004: ID 0572:0320 Conexant Systems (Rockwell), Inc.
and in dmesg:
> usb 1-1.4: dvb_usb_v2: 'DVBSky T330' successfully initialized and connected

But mediaclient doesn't show any device:
> pi@raspberrypi ~ $ sudo /opt/bin/mediaclient -e
> **** List of Media Hardware Devices ****
> pi@raspberrypi ~ $

What could be the problem?
Thanks. idefixx

This does not seem to be our device. It is using the Conexant USB ID.
