| 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). |
