Hi,
I have a PCI video capture card, and the command `lspci` tell me the
following info:
00:09.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
In the kernel source, I compiled the module saa7146.ko and saa7146_vv.ko.
Those modules were inserted into kernel successfully.
But I can't find any new device file in /dev.
Can you tell me the reason?
Does the saa1746 module plays as a common driver for all the device
with that chip?
Thanks!

The saa7146 is a generic chipset that is used on quite a few different
cards. You only compiled and inserted the generic driver core for the
saa7146.

No.
You are missing the extension module for the specific card you have.
For example, if you have a so-called "Multimedia eXtension Board", you
need to insert the "mxb.ko" driver as well.
Please tell me what kind of card that is, ie. brand, manufacturer, card
id etc. so I can tell you if there is a driver that supports it or not.
