iOS: Can third party app see USB descriptors?

We have a USB dongle that would like to connect to the iPhone for power (using USB-C). Since it is not MFi, we will then use bluetooth for communication between the dongle and an app.

When doing bluetooth pairing between the dongle and iPhone, it would be ideal to only see the dongle that is plugged into the iPhone listed in the app. This is to avoid connecting to other dongles that may be in the area.

We think this could be possible using USB descriptors. We assume the iPhone can read the USB descriptors for non-MFi dongles.

Our question is, can our app see the USB-descriptors of the dongle? Is iOS able to pass that info to the app?

Then, we could have a unique USB descriptor for each dongle and the app could only list bluetooth devices with that descriptor (effectively filtering out any other dongles in the area).

Any help and/or feedback is greatly appreciated :)
