Dear all,
I think this is a bug.
In summary: I have a Hauppauge Nova-T 500 dual-tuner DVB-T PCI
card that is not recognised by the DVB driver because it has a
strange USB ID. When the source is edited to force recognition
of the card as a Nova-T 500, it works.
I had some spare time this weekend so decided to upgrade the OS
on the house MythTV box, add a DVB-T tuner card, and swap
architecture to amd64 distribution from i386. I now have Debian
4.0 (etch) for amd64, running the current stable 2.6.18-5-686
kernel. Following the linuxtv wiki page for this card, I
downloaded the driver with mercurial and compiled it
against my kernel. I needed to create a symlink from
/lib/modules/2.6.18-5-amd64/source to /lib/modules/2.6.18-5-amd64/build
as the driver expected 'source', otherwise the build and install
was clean and smooth. dvb-usb-dib0700-03-pre1.fw is in place. I
am in the United Kingdom and therefore am using PAL-I.
BTW I know I have an early-ish model Nova-T, definitely not the
"Diversity" card. FWIW these are the markings on my card:
WinTV-NOVA-T-500
DVB-T 99101 LF
Rev D8B5
Initially the card doesn't work. When dvb-usb-dib0700 is
modprobed, this all that appears in dmesg:
dib0700: loaded with support for 5 different device-types
usbcore: registered new driver dvb_usb_dib0700
That's it, just the two lines. Searching around this problem, the
penny dropped when I saw talk about a change to the USB ID of the
Nova-T cards with the unsupported "Diversity" revision - my card
doesn't have a Hauppauge ID it seems:
$ lsusb
Bus 006 Device 001: ID 0000:0000
Bus 005 Device 002: ID 10b8:0066 DiBcom
Bus 005 Device 001: ID 0000:0000
Bus 003 Device 002: ID 413c:2003 Dell Computer Corp.
Bus 003 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
(Verbose lsusb output below. DiBcom is thecard obviously, the
other item is a USB keyboard.)
Back to the source, I edited linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h so
that card 10b8:0066 is recognised as a Hauppauge Nova-T 500.
When recompiled, the driver now recognises and initialises the
card and /dev/dvb is populated correctly. dmesg now looks
normal:
dib0700: loaded with support for 5 different device-types
dib0700: firmware started successfully.
dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)
DVB: registering frontend 0 (DiBcom 3000MC/P)...
MT2060: successfully identified (IF1 = 1220)
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)
DVB: registering frontend 1 (DiBcom 3000MC/P)...
MT2060: successfully identified (IF1 = 1220)
input: IR-receiver inside an USB DVB receiver as /class/input/input2
dvb-usb: schedule remote query interval to 150 msecs.
dvb-usb: Hauppauge Nova-T 500 Dual DVB-T successfully initialized and connected.
usbcore: registered new driver dvb_usb_dib0700
I can now scan for channels, tune in with tzap and watch a
programme with mplayer, so I conclude the card would be OK if the
driver included the relevant ID in dvb-usb-ids.h.
Thanks,
Andrew Preater
