[linux-dvb] Re: Hauppauge Dec2000-t under 2.6.0 kernel (with CVS updates)

[Stefan Weidt <stefan@sweidt.force9.co.uk>]

Hello,

I'm using 2.6.0 and CVS sources too, they do work fine. I applied the (at the time) 16 patches and did ./makelinks /usr/src/linux I don't know I was simply repeating the same thing but did it anyways. 

The firmware needs to be placed in /usr/lib/hotplug/firmware/dec2000t.bin

Since your kernel compiled I guess you placed it there. Have you enabled hotpluging and installed the hotpluging service?

If not this is probably your problem as everything started working once I did this too.

Enable firmware hotplugging Device Drivers >> Generic Driver Options >> Hotplug firmware loading support (I built mine into the kernel rather than a module)

And install the hotplugging from http://linux-hotplug.sourceforge.net/ or maybe there is a Fedora build?

Adding hotplug as a boot service you should find that the dvb_core and ttusb_dec modules load automatically and the firmware is magically loaded too.

Hope this helps.

Regards 

Stefan
