Hi!

Usually, yes. But "function" is what _manufacturer_ wanted LED to
mean, and "trigger" is how user is using it. I have currently disk
activity LED mapped on scrollock.

There are some mini desktops which have skull LED, probably meant to
be user defined LED. In such cases, user will have to select trigger.

Maybe datasheet does not mention color, but the LED _has_ color.

Not.. really. You don't know from chip specificiations, but you should
know the color as soon as you have USB IDs (because they should tell
you exact hardware). And I believe same is true for PCIe cards. It may
be more tricky if no actual PCIe card exists and it is just a chip
built into generic notebook. (But then, you should have notebook's DMI
id etc...?)

Anyway, you can leave the color field empty if you don't know.

Best regards,
