Some smartphones *may* work with this implementation as well, but likely have limited (broken) drivers,
and likely their manufacturer has not tested such functionality. Some code workarounds could be tried:
The smartphone may only have an ECM driver, but refuse to automatically pick ECM (unlike the OSes above);
try modifying ./examples/devices/net_lwip_webserver/usb_descriptors.c so that CONFIG_ID_ECM is default.
The smartphone may be artificially picky about which Ethernet MAC address to recognize; if this happens,
try changing the first byte of tud_network_mac_address[] below from 0x02 to 0x00 (clearing bit 1).
