And the firmware file is there:

root at torch:/lib/firmware# ls -l /lib/firmware/dvb-usb-af9015.fw 
-rw-r--r-- 1 root root 15913 2010 ápr   16 /lib/firmware/dvb-usb-af9015.fw

Packages installed contains firmwares:

root at torch:/lib/firmware# dpkg --list | grep "firmware"
ii  firmware-ivtv                        0.28                         Binary firmware for iTVC15-family MPEG codecs (ivtv and pvrusb2 drivers)

Can you please look into why the boot process cannot read the firmware file, which exists
and readable?

Scope: Device is unable to use.
Exclusion: Other firmwares are detected and loaded.

User Status:
Reboot didn't help. Poweroff, unplug the computer didn't help.
Unplug the device then replug didn't helped.

The device worked properly under Ubuntu 10.04 LTS Lucid Lynx with (almost) the same kernel
(2.6.35.x).

The system itself is a :

root at torch:/lib/firmware# uname -a
Linux torch 2.6.35.10-3 #1 SMP Mon Dec 27 19:56:08 CET 2010 x86_64 GNU/Linux

Thank you very much for all the help, guideance.
