HVR-950 fails to work under 2.6.26-r3 kernel

[nick88]

Hi,

I'm trying to get a mythtv setup going and have a HVR-950 USB receiver to work with it. The kernel detects the card, but as soon as I try anything with it (such as xawtv), I see nothing on the display. When I was going through dmesg, I saw:

I have checked and I do have under /lib/firmware the file xc3028-v27.fw placed there as per the instructions for setup. What step am I missing?

BTW, wasn't sure if this belongs here or under the kernel & HW formum, but I figure this is the closer match since it is MM related.

TIA...

[poly_poly-man]

deselect all v4l drivers from the kernel, rebuild if necessary.

Extract the firmware using /usr/src/linux/Documentation/video4linux/extract_xc3028.pl - follow the directions at the top of the file.

http://www.linuxtv.org/repo/

checkout the v4l-dvb branch.

build it up

unplug/replug the card.

I've had mine working for quite a while.
