em28xx/em2880-dvb (HVR-950) compilation woes.

[Sastraxi]

Hey all,

Upgraded to Hardy, went smooth as silk. Now the only issue remaining (apart from the dreadful power consumption) is to get my Hauppauge HVR-950 working once more.

I attempted the steps described in the infamous lunapark article (http://lunapark6.com/usb-hdtv-tuner-...v-hvr-950.html) but they do not seem to work for Hardy. Specifically...

... I'm not exactly sure where the problem lies. Has anyone gotten this card (and its digital capabilities that work flawlessly in the 2.6.22 kernel, in gutsy OR hardy) working with Hardy and the 2.6.24 kernel?

[gekkio]

It's a known problem when compiling em28xx with kernels >= 2.6.24.

I managed to get my em2880-dvb working by using this patch from the em28xx mailing list:
http://mcentral.de/pipermail/em28xx/...il/001481.html
It's a very simple Makefile patch, but it worked for me.

Hope it helps!

This link seems to be dead, does anyone know if the file is available elsewhere?

The patch is no longer needed if you download the v4l-dvb-experimental driver.

I have exactly the same problem. The link does not have the patch anymore, its just has the .obj file.
Where can I find the patch.
thanks

[gekkio]

The obj file IS the patch file, it's just named weirdly.

Just download the obj file and patch the source with

patch -p0 < v4l-dvb-kernel-Makefile-2.6.24.obj

So I typed this in the terminal and I have no idea what's going on. It wants to know which file to patch, as I suppose it should.

What file am I patching, and how do I do so? (command-by-command if possible)

Thanks!

There are other issues going on beyond just compiling the driver. Unless somebody else can say different I believe it requires building a new kernel. You may want to hold off until there's a little easier solution then that.

Just to add my 2 cents. I followed gekkio's instructions from post nr 10 of this thread, and have the same experience as others: The machine won't boot if the hvr-950 is plugged in. If I plug it in after the boot, the keyboard stops working (but the mouse still works, I can click on the menu items to shut the machine down.) If I 'modprobe em2880-dvb' and then plug in the hvr-950. it works and I can watch a dvb broadcast with xine. It's a 64 bit AMD machine BTW. (My final problem is finding something I want to watch, but that's not for this forum.)

I had a bit of time today so I tried compiling a new kernel. I stepped up the Hardy kernel to 2.6.25. Once I did that, I was able to compile the v4l-dvb-experimental drivers without any issue. It looks like the patch to the makefile has been added to the repository. Things worked 100%. Not exactly an easy solution but there are guides out there to do each step. It just takes a little time.
