need to initialize twice to discover Aroma Shooter #3

Open danielle-h opened 2 years ago

danielle-h commented 2 years ago

Using Raspberry pi running Linux 10 (buster).

output of java -version:

openjdk version "11.0.12" 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-post-Raspbian-2deb10u1)
OpenJDK Server VM (build 11.0.12+7-post-Raspbian-2deb10u1, mixed mode)
 private static USBASController initAromajoin() {
    USBASController usbController = new USBASController();
    usbController.scanAndConnect();
    if (!usbController.getConnectedDevices().isEmpty()) {
      for (AromaShooter aromaShooter : usbController.getConnectedDevices()) {
        System.out.println("Connected to AromaShooter: " + aromaShooter.getSerial());
      }
    }
    return usbController;
  }

This code never discovers the Aroma shooter in the first time. It always needs to be called twice.

Output first time: (see issue #2)
