libusb does not list iPhone in normal mode

[matteyeux]

Using lsusb for macOS, my iPhone is detected :

 ../lsusb/lsusb
Bus 029 Device 001: ID 8087:0024 Intel Corporation Hub
Bus 029 Device 002: ID 0424:2512 SMSC Hub
Bus 029 Device 003: ID 05ac:8242 Apple Inc. IR Receiver

Bus 000 Device 001: ID 05ac:IPPT Apple Inc. USB 3.0 Bus

But when using a tiny test tool, it seems we have some issues with libusb: device with Product ID 12a8 is not showing.

./usb_test
Vendor:Device = 05ac:828a
Vendor:Device = 0403:8a88
Vendor:Device = 0a5c:4500
Vendor:Device = 0403:6001
Vendor:Device = 05ac:8242
Vendor:Device = 0424:2513
Vendor:Device = 0424:2512
Vendor:Device = 8087:0024
Vendor:Device = 8087:0024

Same results with libusb examples.
It seems to be a known issue on libusb repo.
