Estas pistas fueron encontradas en el archivo USBDeviceConfiguration.plist del último beta de iPhone OS 3.1. El nombre del dispositivo encontrado es iProd.
The iProd1,1 device has been assigned a new productID of 4762 (versus 4757 of iProd0,1) and assigned a different ConfigurationDescriptor of “standardMuxPTPEthernet.” iPhone models also have this designation, and the additional interface identified in the plist for this configuration is “AppleUSBEthernet.” The consensus here seems to be that the new device may have gained high-speed networking capabilities—though the iPhone uses the interface to tether to a laptop to share its 3G connection.
