Discovery what modules are needed by a device

kazuo · 2009-06-01 13:41:27

Hi!

I have laptop with a card reader, it already works but I like to know what modules are needed for it.

I like to create a install hook for mkinitcpio for use it on boot time.

Someone know how to get that info?

Thanks!

Have you tried using extra/hwdetect?

You can also try using lsmod to list all modules currently loaded by the system; the modules you're looking for should be somewhere in that list.

Uhhh... The others option of hwdetect give me nothing. I tried to list all drivers with lsmod and get the info of modinfo but I cannot find a entry for a card reader, at the end of the post is a list (I removed the most obvious).

Is possible that my card reader only uses usb-storage? because the inserted card are recognized as a /dev/sdb.

boot without the card reader, lsmod

insert the card reader, lsmod

compare both outputs?

I cannot remove the card reader, but I can do this with a card, and lsmod show the same output before and after.

I really thinking that my card reader only use usb-storage, tomorrow I'm gonna test it.
