Why doesn't /dev/videox exist?

Post by Neuraleanus »

I have installed a Hauppauge WinTV-HVR-1250 TV Tuner into my Linux Mint 13 (Maya) system. It appears that the card is being detected and the bttv, cx23885, and v4l2_common drivers are getting installed. dmesg indicates:

dmesg | grep -i Hauppauge
[ 6.323683] CORE cx23885[0]: subsystem: 0070:2259, board: Hauppauge WinTV-HVR1255 [card=20,insmod option]

[ 6.470264] cx23885[0]: hauppauge eeprom: model=22111

However, ls /dev fails to show the video devices. Shouldn't they be there? I do not presently have a video source to test the tuner card. I start up Kaffeine and under Television --> Configure Television --> Device 1, it says "Samsung S5H1411 QAM/ Frontend", so it looks like Kaffeine is seeing the TV tuner.
