Answer 1

I have used the following code which works very fine with keyboard, mouse and Mass Storage device to connect with Pandaboard,

  UsbManager usbManager = (UsbManager) getSystemService(USB_SERVICE);
  HashMap<String, UsbDevice> devicelist = usbManager.getDeviceList();
  Iterator<UsbDevice> deviceIterator = devicelist.values().iterator();

  while(deviceIterator.hasNext()) {
    UsbDevice usbDevice = deviceIterator.next();
    Log.i(Log_Tag, "Model     : " +usbDevice.getDeviceName());
    Log.i(Log_Tag, "Id        : " +usbDevice.getDeviceId());
  }

This should work with Arduino too.

The Arduino board needs a driver which needs to be installed before it can be accessed.

I am not sure if you have a port of the driver for Android.
