ACPI offers two methods that allow us to infer whether or not a USB port
is removable. The _PLD method gives us information on whether the port is
"user visible" or not. If that's not present then we can fall back to the
_UPC method which tells us whether or not a port is connectable.
How does this act on bluetooth devices that are (dis)connected by switches
on laptops?
This depends on the bios. From my opinion, the bluetooth is device on the
motherboard so it belongs to hard-wired type.
