Android Question USBManager keeps asking for permission

[Mike1970]

Hi everyone,
I'm using a tablet pc panel with Android.
This panel pc has a USB port that I use to communicate using a USB to TTL converter (YP-01).. the chinese ones you find on Amazon/Aliexpress (Link)... The problem is that using the USB library if the usb is removed and re-inserted it keeps asking for permission everytime! it does not store the fact that was already authorized... is there a method to prevent asking everytime?

Spoiler: Sidequest

Is there a way to Wait For this permission

Public manager As UsbManager
manager.RequestPermission(device)

Thanks in advance

Have you added the XML snippet with the device filter?

hi, yes I pasted this

AddActivityText(main,
<intent-filter>
    <action android:name="android.hardware.usb.action.USB_DEVICE_DETACHED" />
    <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" />
)       
CreateResource(xml, device_filter.xml,
<resources>
    <!-- 0x067b / 0x2303 Prolific PL2303 -->
    <usb-device vendor-id="1659" product-id="8963" />
</resources>
)
SetActivityAttribute(main, android:directBootAware, "true")

But with this code, everytime I plug in the USB automatically starts the application, I do not need this... I only need to remember the permission for the next time I open/insert the USB without have to grant it again

With the device_filter.xml, the expected behavior is that the app will be started with granted permission.

ok... so it could be that the vendor id or product id is wrong?
Where can I find such information?

And what would be the manifest file in the case I do not want to start the application automatically?

Maybe.

Where can I find such information?

You can find it with the UsbHost library or any third party USB app that shows such information.

And what would be the manifest file in the case I do not want to start the application automatically?

Everything possible is documented here: https://developer.android.com/develop/connectivity/usb/host
As far as I remember there is no such option.
