Assigning device identifiers by host identifier availability

A host computing device, comprising:

• a logic subsystem;
• and
• a storage subsystem holding instructions executable by the logic subsystem to:
• receive, from a separate electronic device, a current local identifier of the separate electronic device;
• receive, from the separate electronic device, a full unique identifier of the separate electronic device, different from the current local identifier;
• based at least in part on determining that the current local identifier of the separate electronic device is already assigned to a different separate electronic device having a different full unique identifier, select a host-specific local identifier for the separate electronic device from a set of local identifier values available for assignment;
• and
• based at least in part on determining that all possible local identifier values have been assigned to a plurality of different separate electronic devices, identify a least-recent separate electronic device of the plurality of separate electronic devices that has been least-recently detected by the host computing device, and return a host-specific local identifier corresponding to the least-recent separate electronic device to the set of local identifier values available for assignment.

A method for electronic device identifier assignment at a host computing device, the method comprising:

• receiving, from an active stylus, a current local identifier of the active stylus;
• receiving, from the active stylus, a full unique identifier of the active stylus, different from the current local identifier;
• based at least in part on determining that the current local identifier of the active stylus is already assigned to a different active stylus having a different full unique identifier, selecting a host-specific local identifier for the active stylus from a set of local identifier values available for assignment;
• and
• based at least in part on determining that the active stylus has not been detected by the host computing device for at least a threshold time, returning the host-specific local identifier to the set of local identifier values available for assignment.
