I'm trying to clear up space on my root partition and /lib/firmware is taking up a lot of space. There are a lot of files for devices that I know I don't have, but there's also a lot of files for devices that I don't recognize so I don't know whether or not I need the firmware.
Is there maybe a way to see what firmware files have actually been loaded?

You can check the firmware that is used for your system in the kernel log.
grep firmware /var/log/kernel.logwill give you a nice list of firmware that was loaded since the last log rotation (could be several days)
However since i first posted this, I learned that most of the firmware will be loaded by initrd and that usually does not generate a logfile of what it is doing.
