+Description:
+		Information about whether a given device can be removed from the
+		platform by the	user. This is determined by its subsystem in a
+		bus / platform-specific way. This attribute is only present for
+		devices that can support determining such information:
+
+		===========  ===================================================
+		"removable"  device can be removed from the platform by the user
+		"fixed"      device is fixed to the platform / cannot be removed
+			     by the user.
+		"unknown"    The information is unavailable / cannot be deduced.
+		===========  ===================================================
+
+		Currently this is only supported by USB (which infers the
+		information from a combination of hub descriptor bits and
+		platform-specific data such as ACPI) and PCI (which gets this
+		from ACPI / device tree).
