nova-t problems ?not creating /dev/dvb automatically
« on: February 04, 2006, 03:27:51 pm »
I have recently set up a pluto hybrid system and install a Hauppauge Nova-T DVB card.  It's the newer version, based on the cx-88 chipset.

I'm an experienced mythtv user, and have successfully set-up the card in a mythtv on FC4 and Knoppmyth. The card is installed in the hybrid core and the
cx88 software has been added to the core.

An extract from dmseg shows that the card is detected.
dcerouter_3777:~$ dmesg | grep cx
cx2388x v4l2 driver version 0.0.5 loaded
CORE cx88[0]: subsystem: 0070:9002, board: Hauppauge Nova-T DVB-T [card=18,autodetected]
cx88[0]: hauppauge eeprom: model=90002
input: cx88 IR (Hauppauge Nova-T DVB-T as /class/input/input2
cx88[0]/0: found at 0000:02:09.0, rev: 5, irq: 161, latency: 32, mmio: 0xf7000000
cx88[0]/0: registered device video0 [v4l2]
cx88[0]/0: registered device vbi0
cx2388x blackbird driver version 0.0.5 loaded

The mythbackend doesn't seem to be able to interact with the card- it gives the errors "Frontend ID: Could not open card #0! Subtype: No such file or directory" when I try and use it.

On checking in /dev it appears no /dev/dvb entries exist.   I recall when setting up the card on another system I had to create some udev rules which don't appear to be in Pluto by default.  

Could others comment on whether they have the Nova-T card running in Pluto, and whether it works out of the box or if you had to tweak it manually?

fixed: auto-creation of /dev/dvb with nova-t card

For the benefit of anyone searching the archives I can confirm that the Hauppauge Nova-T DVB card works fine in 0.38.

I haven't got the EPG data to work yet, but live-TV in Myth (0.19) is working fine.
