How to update the hardware autodetection database

[benlau]

I got a bt878 card too, knoppix 3.4 and kernel 2.6.5.

I don't need to pass a parameter to the i2c-... but to the bttv-module:

modprobe bttv card=42 tuner=1

Of course card will differ on your system, and tuner maybe too.
Since my desktop is shutdown and closed, I can't tell you the manufactor.

Benlau: It needs 20 min to boot your system??? How fast is your processor?
It needs 30 sec to boot mine!

That is not the problem of my computer , 99.99% of time spent on the initializing of bttv module(i2c-algo-bit probing in fact). It boots quite fast(around 40s?)when turned bit_test on. However , the bttv module won't work until I passed card=77 to it. So I think the hwsetup program should be enhanced for bttv card...
