According to wiki on linuxtv:
---------
TerraTec Cinergy Hybrid T USB XS is a USB 2.0 DVB-T device.
There are apparently several slightly different versions of the Cinergy Hybrid T USB XS.
Based on:
Empiatech Em2880 usb bridge
Xceive XC3028 tuner and analog IF demodulator
Zarlink DVB-T demodulator (ZL10353 or MT352, depending upon version)
Both versions of the product that have USB ID 0ccd:0042 are supported in Linux kernel 2.6.31.

I have no idea has detect different versions, I have only the version with demodulator MT352 which work with EM2880.
