bttv and dvb issues

I am having trouble getting a tv dvb card working.

I am using the bttv driver which is fine, with a twinhan card, no problem so far. However, when it loads I sometimes get
bttv0: add subdevice "dvb0"

with no tuner. I have read some where a doc which seems to suggest I need to load a dvb module, dvb_bt8xx with modprobe which would then allow access to the digital tuner, but can't seem to get that on the current kernel.

Any thoughts?

Kind regards

Re: bttv and dvb issues

Are you sure bttv is the right module? Afaik, there are plenty of dvb modules inside the 2.6 kernel. Let me jsut switch from kernel 2.4 to kernel 2.6, remove my old bttv hauppauge card, and let's see what modules I have to take to run my dvb-t usb device. I will tell you about it then.


I have to use dvb_core, cinergyT2, and the nodes read /dev/dvb0.demux0  /dev/dvb0.dvr0  /dev/dvb0.frontend0  /dev/dvb0.net0.

Re: bttv and dvb issues

me too. same card (twinhan) which seems correctly identified by the kernel.

input: USB HID v1.10 Keyboard [Twinhan Tech Remote Control] on usb-0000:00:02.0-2
input: USB HID v1.10 Mouse [Twinhan Tech Remote Control] on usb-0000:00:02.0-2
bttv: driver version 0.9.15 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
ACPI: PCI interrupt 0000:01:09.0[A] -> GSI 17 (level, high) -> IRQ 17
bttv0: Bt878 (rev 17) at 0000:01:09.0, irq: 17, latency: 32, mmio: 0xe0000000
bttv0: detected: Twinhan VisionPlus DVB-T [card=113], PCI subsystem ID is 1822:0001
bttv0: using: Twinhan DST + clones [card=113,autodetected]
bttv0: gpio: en=00000000, out=00000000 in=00f3ffff [init]
bttv0: using tuner=4
bttv0: add subdevice "dvb0"
bt878: AUDIO driver version 0.0.0 loaded
bt878: Bt878 AUDIO function found (0).

the trouble is the configuration with udev: the tools need to find "/dev/dvb/*" but the standard udev configuration does not build automatically these nodes...
someone can help us posting a working udev configuration?
