Permission to mUsbDevice failed

[GoogleCodeExporter]

I was receiving a null pointer error as getDeviceDescriptor() was called before 
mUsbDevice was set. I have now addressed that, however 
if(!mManager.hasPermission(mUsbDevice)) in getDeviceDescriptor() is returning 
false. 

Does the code provide for permission to be granted? I am a newbie and have seen 
some code to do this on the android site but am unsure how to implement it.  
Many thanks.

modify Android Manifest:

add feature:
<uses-feature android:name="android.hardware.usb.host" />

change activity declaration:

        <activity
            android:name=".SandboxAppActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <intent-filter>
                <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />                
            </intent-filter>

            <meta-data
                android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
                android:resource="@xml/device_filter" />
        </activity>
