How to use ATS (Beagle USB Analyzer) to connect iPhone 15?

Hi,

We want to connect the iPhone 15 to Accessory Test System (ATS) for traffic capture. The iPhone 15 is a USB-C iOS device. In ATS User Guide, the iAP-over-USB (USB-C) setup mentions:

For iAP-over-USB accessories which can connect to USB-C iOS devices, you only need to connect a Beagle USB 480 analyzer.

The Beagle USB 480 analyzer USB-A port should be connected to the USB device, the USB-B port should be connected to the USB host. Connect the equipment as shown.

We use the following setup with Beagle USB 480 analyzer:

[Beagle: USB-B port] <-- USB-B-to-TypeC cable --> [iPhone]
[Beagle: USB-A port] <-- USB-A-to-USB-A cable --> [Accessory]

But, the Beagle USB Analyzer in the ATS app cannot find the iPhone attached.

Is the above setup correct? How to connect the iPhone 15 to the Beagle USB 480 analyzer?

Does anyone know the iAP-over-USB (USB-C) setup? Thanks for help.
