Constructors

constructor(application: Application, dispatchers: CoroutineDispatchers, processLifecycle: Lifecycle, usbBroadcastReceiverLazy: Lazy<UsbBroadcastReceiver>, usbManagerLazy: Lazy<UsbManager?>, usbSerialProberLazy: Lazy<UsbSerialProber>)

val serialDevices: StateFlow<Map<String, UsbSerialDriver>>

Creates a USB serial connection to the specified USB device. State changes and data arrival result in async callbacks on the supplied listener.

True when the app already holds USB permission for device, so a request round-trip can be skipped.

suspend fun pokeDtr(driver: UsbSerialDriver, holdMillis: Long): Boolean

Opens driver's port, asserts DTR/RTS for holdMillis, and closes it again.
