The firmware isn't being loaded because the driver isn't being loaded.  
You should see messages when the driver gets loaded into the kernel and 
then various other messages as it goes through its initialization 
process.  The messages you do have here only come from the USB stack.  
There appears to be no attempt to autoload the driver.

Hmm, well it's there in the right spot, but what's with the .gz 
extension?  Last time I checked, kernel modules have to be uncompressed 
in order to be loaded.  Try this as root:

cd /lib/modules/2.6.31.12-desktop586-lmnb/kernel/drivers/media/video/pvrusb2
gunzip pvrusb2.ko.gz
depmod -a

Now unplug and re-plug in your tuner.  Then do:

lsmod | grep pvrusb2

You should see a line that has "pvrusb2" in it.  That's evidence that 
(this time) the driver has been loaded.  Look at your dmesg output again 
and see if you can find messages from the driver this time.

Yes, that's definitely needed as well.

Does anyone know if Mandriva something strange with kernel modules to 
save space?
