No /dev/dvb with 2.6.32.7 created [SOLVED]

[holm74]

Hi there,

I try to get my (Cinergy Hybrid T USB XS) working (0CCD 005E) Anyway: compiled necessary modules like dvb_core, em28xx, em28xx_alsa and em28xx_dvb into the 2.6.32.7 kernel.
Plugin in the USB-Stick it gives me following dmesg:

As you can see also the /lib/firmware xc3028-v27.fw will be loaded. Everything will be recognized.

BUT what is missing is the dvb device under /dev/dvb.

/dev/video0 and /dev/vbi0 will be created but no /dev/dvb.

I googled around: All solutions directs to em28xx-new. But these modules are not supported anymore (specially no patch for the 2.6.32 Kernel).

As modinfo em28xx tells me also alias: usb:v0CCDp005Ed*dc*dsc*dp*ic*isc*ip* is supported - as you can see 0CCD 005E is my DVB-T Stick. What I am also wondering about is that after plug out the stick rmmod em28xx, rmmod em28xx-alsa and rmmod em28xx-dvb - and plug in again only em28xx em28xx-alsa will be loaded. Nevertheless I also tried to modprobe em28-xx card=82 - but still no /dev/dvb.

Thanks for any advices.

Support for this tuner (I have it too, very nice little device) was added in 2.6.33. For 2.6.32, apply this patch:

Thanks Gusar, you are a guru. This solved my problem. I don't really understand why Google showed me only the em28xx_new bullshit and all its non working links.

Appreciate it.

Probably you missed its firmware in /lib/firmware

have a look at http://www.linuxtv.org
