Hardware interrupt API for Linux

Question

When I am going to connect device through USB port, I want to detect it immediately. I am searching for a Java API, my main target is Linux OS.

Does anyone know an API like that?

I suspect you will need to poll a command which lists USB devices. — Peter Lawrey, Nov 19 '12 at 09:05
@PeterLawrey Can you please elaborate it. Any reference link? — Sachin J, Nov 19 '12 at 09:07

You can do something like this:

try {
    String command = "lsusb"; // you may add some param if you want
                              // or use adb for instance
    Process child = Runtime.getRuntime().exec(command);

    // Get output stream to write from it
    OutputStream out = child.getOutputStream();

    // TODO parsing lsusb output

    out.close();
} catch (IOException e) {
}

Thanks for reply. Its detects attached mouse. Let me clear my scenario , when I am connecting an android os device to my machine I want to fire an event which will show that device is found. – Sachin J Nov 19 '12 at 10:07
Try replace `lsusb` with `adb devices | awk 'NR>1 {print $1}'`. Pay attention that you need installed `adb` – CAMOBAP Nov 19 '12 at 11:47

would also consider monitoring USB events by DBus interface

there is DBus-Java library here and a similar thread but on python here
