Terratec Cinergy Hybrid T USB XS
Recently, I bought such a USB TV Receiver. This is a little neat USB-Stick which is capable of receiving analog TV and DVB-T. Unfortunatly, I could not find an Linux driver for this beast by Januar 2006. So, I started to do some research on this USB-Receiver.
But since end of march there is a working linux driver. Thanks a lot to Markus Rechberger who did develop this driver.
Takeing it apart
I opened the case and found 2 PCBs almost coverted by shieldings. The only chip I could see was a Zarlink ZL10353. All others are under the shieldings. I got my soldering iron and took the beast apart. Here are the pictures:

Snooping the Windoz driver
I did log the USB traffic between Windoz XP and the stick on my Laptop.
After I installed the driver software I saw 3 new device with the same VID:PID (0CCD:0042) in usbsnoop.
Actually, you see 6. I have two connectors and as I plugged it in to the second one I got an other 3 entries.
I used the apps from Terratec to do the snoops:
- "Cinergy TV" for analog TV
- "Cinergy Digital 2" for DVB-T
I logged only one devices at at time. And I never saw something on the "USB-Verbundgerät".
ANALOG ("Cinergy TV"):
Cinergy Hyprid T USB XS:
- After plug-in, log size is 696035 Bytes
- After start of "Cinergy TV" (analog) file size grows until I stopped the app. I started channel scan, but the app is always streaming -> the noise?
Here are the output of usbsnoop Cinergy_Hyprid_T_USB_XS_analog.log and after I parsed it with usbanalyze.pl Cinergy_Hyprid_T_USB_XS_analog_parsed.log
USB-Audiogerät:
- After plug-in, log size is 22440 Bytes
- After start of "Cinergy TV" (analog) file size grows until I stopped the app. I started channel scan, but the app is always streaming -> the noise?
Here are the output of usbsnoop USB-Audiogerat_analog.log and after I parsed it with usbanalyze.pl USB-Audiogerat_analog_parsed.log
DVB-T ("Cinergy Digital 2"):
Cinergy Hyprid T USB XS:
- After plug-in, log size is 696222 Bytes
- After start of "Cinergy Digital 2" (DVB-T) file size grows until I stopped the app. I started channel scan, but the app is doing something I don't think streaming.
Here are the output of usbsnoop Cinergy_Hyprid_T_USB_XS_digital.log and after I parsed it with usbanalyze.pl Cinergy_Hyprid_T_USB_XS_digital_parsed.log
USB-Audiogerät:
- After plug-in, log size is 21292 Bytes
- After start of "Cinergy Digital 2" (DVB-T) nothing happend to the log file
Here are the output of usbsnoop USB-Audiogerat_digital.log and after I parsed it with usbanalyze.pl USB-Audiogerat_digital_parsed.log
