iOS / iPhoneOS 13 device capture
I'm doing some really unsupported/stupid stuff where I compiled libusb for Darwin in XCode for iPhoneOS. That works fine, but the hotplug / device resolution doesn't seem to detect devices (it returns nothing) as well as your code, which returns

The USB interface is obviously detected by the iPhoneOS kernel. Could you throw up a small snippet on how somebody might, say,
- open the interface / claim it
- perform controlTransferOut / controlTransferIn against it
- perform transferIn / transferOut against endpoints from that interface
This would open a massive world in iOS/iPhoneOS development where USB device support isn't really documented but is actually secretly supported.

I think this means the functionality we need to do anything other than list the device is not supported/permitted but I'd be curious to hear your thoughts.
