[linux-dvb] Kworld USB 2870 DVB-T Receiver

[Tim Ansell]

Hello,

I recently brought a USB DVB-T Receiver. I would now like to get this
device working under Linux (my favourite OS :). 

It is made by Kworld and is called a "USB 2870", it is a digital only
device (not to be confused with the "USB 2880" which is a dual
digital/analogue device). I believe it is based on EM28xx chipset as the
window driver has the following files,

./emBDA.inf
./emBDA.sys
./emOEM.sys
./emPRP.ax
./emWHQL.cat
./TVEpaDrv.ini

There appears to be work on a driver for these chip sets in the DVB
tree. How far along is this driver and is it likely to work with this
device (after a bit of work)? 

>From what I understand the first job would be to add an entry to the
"em28xx_boards" and "em28xx_id_table" for my card. I've included the
information from the embda.inf which is related to my device at the end
of this email as I believe this should contain the information needed to
construct this entry?

I can include output of lsusb and usbview if it makes life easier.

Obviously I don't expect you to do all the work to make this card work
(specially since you don't have one!). However, I haven't coded for
anything like a DVB card before and would appreciate any help.

Thanks for your help!
