[linux-dvb] Hauppauge Nova-T-500 - No frontend attached

Hi folks,

I'm having problems with getting my Hauppauge Nova-T-500 dual DVB-T
tuner running. If it is relevant, it is the half-height OEM version,
rather than the retail version.

The box is a Dell Dimension 5000, initially running Ubuntu 6.10. Because
the card needs a kernel >= 2.6.19 I upgraded to Ubuntu 7.04 with the
2.6.20 kernel. I've followed what look like two reasonably detailed
guides to getting this card working

http://www.omskakas.se/2007/01/howto-hauppauge-nova-t-500-pci-under-linux.html 


and

http://wiki.efficientpc.co.uk/index.php/Install_Nova-T_500_On_Ubuntu_Linux

I've worked through both, carefully following all of the steps.

When I load the dvb-usb-dib0700 module, I get;

mythtv at brianclough:~$ sudo modprobe -v dvb-usb-dib0700
insmod
/lib/modules/2.6.20-15-generic/kernel/drivers/media/dvb/frontends/dib7000p.ko
insmod
/lib/modules/2.6.20-15-generic/kernel/drivers/media/dvb/frontends/dib7000m.ko
insmod
/lib/modules/2.6.20-15-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb-dib0700.ko 

force_lna_activation=1

which looks as expected, but I find the following in dmesg;

[ 129.916740] dib0700: loaded with support for 2 different device-types
[ 130.003164] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm
state.
[ 130.003236] dvb-usb: will pass the complete MPEG2 transport stream to

[ 130.090824] dvb-usb: no frontend was attached by 'Hauppauge Nova-T 500

[ 130.090834] dvb-usb: will pass the complete MPEG2 transport stream to
the software demuxer.
[ 130.091231] DVB: registering new adapter (Hauppauge Nova-T 500 Dual
DVB-T).
[ 130.091941] dvb-usb: no frontend was attached by 'Hauppauge Nova-T 500
Dual DVB-T'
[ 130.091951] dvb-usb: Hauppauge Nova-T 500 Dual DVB-T successfully
initialized and connected.
[ 130.092319] usbcore: registered new interface driver dvb_usb_dib0700

I think the relevant is the "no frontend was attached". When I run
mythtv-setup, I can only find the other tuner (a USB twinhan).

The twinhan usb DVB-T box is successfully working. If I look in
/dev/dvb/adapter2 I find demux0, dvr0, frontend0 and net0. If I look in
/dev/dvb/adapter0 or /dev/dvb/adapter1 I only see demux0, dvr0 and net0.

If it is relevant the output of lsusb and "lsmod | grep dvb" is attached.

So what am I doing wrong? Any tips, advice or links that would help me
diagnose or solve the problem will be gratefully received.

Regards,
