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). |
