有關 USB_NET_CDCETHER : config USB_NET_CDCETHER tristate "CDC Ethernet support (smart devices such as cable modems)" depends on USB_USBNET default y
所以要 enable USB_USBNET: config USB_USBNET tristate "Multi-purpose USB Networking Framework" select MII 還有，這些是屬於... menu "USB Network Adapters" depends on USB && NET
