| 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). |
