Hi Alan,
actually this question has been raised by several people in the past
already. Copy/pasting the latest reply I have sent on this topic
===
mostly this is because we don't want to bother users with asking for every
single quirky device/vendor, as there are unfortunately a lot of them.
Usually compiling everything in doesn't waste runtime footprint (the
modules don't get loaded unless needed), and they don't cost too much disk
space either.
And if you really want to disable them, CONFIG_EMBEDDED allows you to do
that.
Please see last paragraph on
