Thomas,

Take a look in the v4l-dvb tree...  We already have a driver for em2800, 
em2820, and em2840 usb controllers... You may want to speak to mchehab, 
mrec, cavedron, or sasha, to find out if support can be added for 
em2880, or if it may already be supported by the em28xx driver...

linux/drivers/media/video/em28xx

OTOH, em28xx does not yet have a dvb layer.... This can be added, but so 
far we havent encountered any devices that call for it, until now.

^^ this is a very popular tuner, but unfortunatly, is not supported in 
linux at this time, due to lack of proper specs required to create a 
driver... I'm sure some other developers have run into this in the past 
as well... Unfortunately, I dont have an answer for this tuner, although 
supporting it would open up the possibilities of supporting many more 
devices.

^^ never heard of it.... Zarlink has some other demod's that ARE 
supported, however... Maybe a driver can be written for this... /me 
isn't sure.

^^  might this be a TVP5150 ?  (supported in v4l)

^^ not sure

...well thats SOME information for you... although not quite the 
greatest news, but I hope this helps.
