Methods inherited from FuDevice (156)
fu_device_activate

Activates up a device, which normally means the device switches to a new firmware version. This should only be called when data loss cannot occur.

Available since: 1.2.6

fu_device_add_child

Sets any child device. An child device is logically linked to the primary device in some way.

Available since: 1.0.8

fu_device_add_counterpart_guid

Adds a GUID to the device. If the guid argument is not a valid GUID then it is converted to a GUID using fwupd_guid_hash_string().

Available since: 1.1.2
