Sometime ago, I bought this usb hybrid tv tuner with FM radio, an Asus 
My-Cinema U3000Hybrid, which considering some Googling I've made on the 
subject seems to be a tuner primarily marketed to eastern and southern 
Europe markets.

Asus is very scarce concerning information related to the device 
specifications. "Official" information is here 
http://www.asus.com/products.aspx?modelmenu=2&model=1639&l1=18&l2=84&l3=254&l4=0

and here  
http://www.asus.com.au/products.aspx?l1=18&l2=84&l3=254&l4=0&model=1639&modelmenu=2

why the second link mentions a so-called "IXCEIVE" tv tuner and the 
first one omits it beats me completely.

The device seems unsupported out-of-the-box in my OpenSUSE 11.0 
(2.6.25.11 kernel) and when I tried googling about linux support I found 
a complete vacuum concerning it. The official support page (forum) has 
some questions related to linux support, all left unanswered. Also, I 
tried inquiring the direct email help support from asus, getting 
non-clear answers (all the operator told me was that "the specification 
of TV Tuner is Philips"). I was also surprised to see that this device 
is not mentioned in the mailing lists.

I think there is some confusion in the available information concerning 
the chips used in this device. According to other resource I found: 
http://www.senorg.ro/tv-tunere/asus , a Philips chipset seems to be used 
in older models, some analog only. In the other hand I since xceive 
tuners seem to do the job on both the analog and digital sides, I don't 
see the need to add a a DibCom chipset as well... As so I'm a little 
sceptical about the information available. I was thinking about trying 
the xc3028 or the other members of the xceive family of drivers but I 
was not sure as to em28xx would be an important part to add as well or 
what would be its role in it...

I could think of opening the encased device but I'd preferably rather 
not, as it normally turns out to be irreversible...

Thanks in advance,
