On routinely updating my Debian system, I've never took the time to pick which firmware packages I do really need; basically I have them all installed, and always up-to-date.
I've been wondering how can I pick which ones I do really need. I was thinking of using every device I have in my system (even the ones I rarely use like bluetooth, ethernet, camera, touchpad, multimedia keys and so on) and look at the list of loaded firmware.
Is there an easy way to find out which firmware is currently loaded, or were loaded since last kernel boot?
