LinuxQuestions.org - [SOLVED] question about lspci -v doesn't show for some devices its drivers.

Hello everybody, first of all, i am spanish so, sorry for my english.

My question is, that in some devices, when i do lspci -v, doesn't show the kernel drivers. An example:

$ lspci -v

For device 00:01.0 doesn't show the kernel driver and the same for 00:02.0, 00:02.1, while for the rest the comand show its driver.

Searching in google i found that somebody has shpchp driver for device 00:01.0. Why does this information isn't showed to me?

All this is because i want to compile the kernel and i need to know the drivers.

Thanks in advance.
