Comment 12 for bug 99180

I have a similar problem with 7.04 (2.6.20-16-generic) and an Intuix S-810 Lite-On based (ID 04ca:f001 Lite-On Technology Corp.) dvb-t stick, as the frontend never gets loaded:

[ 24.080000] dvb-usb: found a 'LITE-ON USB2.0 DVB-T Tuner' in cold state, will try to load a firmware
[ 24.412000] dvb-usb: downloading firmware from file 'dvb-usb-dibusb-6.0.0.8.fw'
[ 24.500000] usbcore: registered new interface driver dvb_usb_dibusb_mc
[ 24.620000] dvb-usb: generic DVB-USB module successfully deinitialized and disconnected.
[ 26.512000] dvb-usb: found a 'LITE-ON USB2.0 DVB-T Tuner' in warm state.

Here are two others:

However, the 'solution' referred to, on
http://linuxtv.org/hg/~mkrufky/megasky/
has been integrated into the drivers.

So I tried Crevany's suggestions, which can be found on
http://www.linuxtv.org/wiki/index.php/How_to_install_DVB_device_drivers
but compiling failed:

Might this be a hardware issue? How to find out?
