Answer 1

You may have to take help of linux kernel so I think just execute one simple command that can give you list of devices connected to your device

Here it is

Process process = Runtime.getRuntime().exec("cat /proc/devices");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

or you can use udevinfo I dont know in details about it but google is there for you

Answer 2

If you have honeycomb or above use the USB Manager Service

    UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
    HashMap<String, UsbDevice> devices = manager.getDeviceList();
