//here is the class for the another USB.. `package com.mmm.chk.callback; import android.os.Process; import android.util.Log; import com.hoho.android.usbserial.driver.UsbSerialPort; import java.io.IOException; import java.nio.ByteBuffer; public class SerialInputOutputHIDManager implements Runnable { public enum State {...

but this is only working after rebooting the android device else it is not working even when the app is destroyed and again re created.

is there any way possible to restart the communication of that USB port.

yeah i do checked this but still one of the USB went non-responsive applied all the tactics you provided but still the same issue in one of the USB's
