Thank you very much,
I've opened my brand-new device with a pair of scissors and found that
inside there are the following components:
- intel WJCE6230
- maxlinear MXL5003S.

I've done also a bit of searching, and found this:
http://download.intel.com/design/celect/refdesign/31543301.pdf

It's a reference design for a PC-TV Usb "Stick". It's very similar to
what I saw when I opened mine.
On the second page it's possible to read:

Supported by:
– Data sheet and design manual for the
Intel CE 6230 DVB-T demodulator
– Bill of material, schematics and diagrams
– Full software GUI for operational performance
verifi cation testing
– Source-code driver software including BDA
MCE binary drivers (provided under license by
LN Systems UK Ltd.*)
– Performance test results including: NorDig
Unified 1.0.2, USB 2.0, ESD and EMC

AND my CE6230 driver (under windows) has two files which are not
digitally signed by Microsoft, and whose copyright is "LN Systems
Limited". I may be wrong, but I think that my device is provided with
Windows drivers which are very similar to the ones proposed by intel
on their reference design.

So, the matter would be getting this stuff from intel.

Paolo
