If a device is ++ * configured, it is allowed to exchange packets with the host. ++ * Fancier models would mean not working on some hardware. ++ * ++ * - Minimal manufacturing control: no IEEE "Organizationally ++ * Unique ID" required, or an EEPROMs to store one. Each host uses ++ * one random "locally assigned" Ethernet address instead, which can ++ * of course be overridden using standard tools like "ifconfig". ++ * (With 2^46 such addresses, same-net collisions are quite rare.) ++ * ++ * - There is no additional framing data for USB. Packets are written ++ * exactly as in CDC Ethernet, starting with an Ethernet header and ++ * terminated by a short packet. However, the host will never send a ++ * zero length packet; some systems can't handle those robustly. ++ * ++ * Anything that can transmit and receive USB bulk packets can implement ++ * this protocol. That includes both smart peripherals and quite a lot ++ * of "host-to-host" USB cables (which embed two devices back-to-back). ++ * ++ * Note that although Linux may use many of those host-to-host links ++ * with this "cdc_subset" framing, that doesn't mean there may not be a ++ * better approach. Handling the "other end unplugs/replugs" scenario ++ * well tends to require chip-specific vendor requests.
