+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).
