0004 Description:
0005 Information about whether a given device can be removed from the
0006 platform by the user. This is determined by its subsystem in a
0007 bus / platform-specific way. This attribute is only present for
0008 devices that can support determining such information:
0009
0010 =========== ===================================================
0011 "removable" device can be removed from the platform by the user
0012 "fixed" device is fixed to the platform / cannot be removed
0013 by the user.
0014 "unknown" The information is unavailable / cannot be deduced.
0015 =========== ===================================================
0016
0017 Currently this is only supported by USB (which infers the
0018 information from a combination of hub descriptor bits and
0019 platform-specific data such as ACPI) and PCI (which gets this
0020 from ACPI / device tree).
