This is determined by its subsystem in a 7 bus / platform-specific way. This attribute is only present for 8 devices that can support determining such information: 9 10 =========== =================================================== 11 "removable" device can be removed from the platform by the user 12 "fixed" device is fixed to the platform / cannot be removed 13 by the user. 14 "unknown" The information is unavailable / cannot be deduced. 15 =========== =================================================== 16 17 Currently this is only supported by USB (which infers the 18 information from a combination of hub descriptor bits and 19 platform-specific data such as ACPI) and PCI (which gets this 20 from ACPI / device tree).
