Answer the question once and chevk the checkbox.
Your app should be the default then and you do not need to answer again. Or not?

Of course, but when power on or restarting the tablet, it asks again for the USB permissions when starting the program.

Have you added the USB device definition to the manifest editor?

Yes Erel I copy this from UsbSerialDemo example...

AddActivityText(main, <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" />)

but a compiler error shows... i check the libraries... and dont know what is it!

B4A version: 7.01
Parsing code. (0.00s)

Generating R file. Error
AndroidManifest.xml:31: error: Error: No resource found that matches the given name (at 'resource' with value '@xml/device_filter').

Thank's
