Technically ECM and 556 EEM are designed for different applications. The ECM model extends 557 the network interface to the target (e.g. a USB cable modem), and the 558 EEM model is for mobile devices to communicate with hosts using 559 ethernet over USB. For Linux gadgets, however, the interface with 560 the host is the same (a usbX device), so the differences are minimal. 561 |
