Unable to open external port No such device error
<p>I am a beginner level developer in android. I got an error in device not in emulator.
I have used sony ericsson xepria x10i. my application works well but it takes more time to display the first activity.</p>

<pre><code>E/dun_service(15640): Unable to open external port /dev/ttyHSUSB0 : No such device

W/ActivityManager(  958): Launch timeout has expired, giving up wake lock!
</code></pre>

<p>How can i fix and give kind advice?</p>
