Terratec T USB XXS 0ccd:00ab device

Terratec T USB XXS 0ccd:00ab device

Hello, I've just subscribed this list. I'm normally using knode to read news, 
but somehow I can not pull the groups etc from the vger server.

I also tried to post to linux-dvb mailing list, but found out that it moved 
here. If you think I need to know something explicitly about participating to 
the list, please let me know.

The issue I'm facing is that my old TV card (HVR900) stopped working, so I 
googled around and decided to buy Terratec T USB XXS, reading it was 
supported in dvb_usb_dib0700

However after installing the card (usb-stick) it was not recognized (my one 
has product id 0x00ab and not 0x0078), so I googled again and found a hint to 
change the device id in dvb_usb_ids.h which was working for other Terratec 
card.

I pulled the latest v4l-dvb code and did it (perhaps I could have done it in 
the kernel 2.6.31), compiled, installed and it started working.

However I can not handle udev to get the remote control links created 
correctly. Can someone help me with it? How can I provide useful output to 
developers to solve the issues with ir? I read and saw that ir control keys 
are coded in the driver, so if the ir part of the 0x00ab card is different, 
how can I get a useful information that can be coded for this card? Who is 
doing the work at linux-dvb?

I read there are other people, returning the cards to the seller, because it's 
not working/supported by linux, which does not seem to be really true.

Luckilly I have a bit kernel experience and good C knowledge and could do 
testing if somebody can have a look at the issues - the code is completely 
new to me so that I prefer to be an alpha tester for the device.

thanks for patience in advance and kind regards

Basically, all you need to do is to enable IR debug, when loading em28xx module
and see what's the scan code for each pressed key on the IR. Then edit
ir-keycodes.c, adding a new table there, and edit em28xx-cards.c to add a new
board entry with the new code, with the new IR table.
There's a page for Remote Controllers at linuxtv.org wiki showing what keycode
names should be used for each key.



Cheers,
Mauro

Something is completely wrong with this "linux-dvb" list. I subscriubed there before and people are posting - I'm getting the mails.

It seems there are two device ids covering the same card model

no dvb_usb_dib0700 is not part of the mainstream kernel yet

http://www.linuxtv.org/wiki/index.php/Template:Making-it-work:dvb-usb-dib0700

helped solve the issues

however you don't get this page listed in google under top ten (at least on my pc)

This is really stupid idea to give up something that easily.

The offer still holds - someebody should change the code to make it work
