Enum Class ScanMode
- All Implemented Interfaces:
Serializable
,Comparable<ScanMode>
,Constable
Provide a collection of different device enumeration scanning modes so that
device attach/detach events can be generated.

NO_SCAN
Equivalent to scan interval of zero. -
SCAN_AT_FIXED_INTERVAL
Trigger continuous scan at given interval. -
SCAN_AT_FIXED_INTERVAL_WITH_PAUSE_AFTER_WRITE
Trigger continuous scan at given interval but introduce a pause after a write operation to allow the device time to process data without having to respond to further enumeration requests. This can be a useful strategy for handling devices with constrained processing power and/or limited USB stacks. Note this will affect the time to generate a device attach/detach event since scanning will be paused.
