I don't know anything to be useful, sorry. It's just part of the USB protocols for devices that want to look like ethernet and the Linux kernel has drivers for that. When I plug my Android phone into a PC via USB, I get to select on the phone what it should use USB for. If I select 'USB tethering' then the 'dmesg' output on the PC shows usbcore: registered new interface driver cdc_ether rndis_host 2-2:1.0 usb0: register 'rndis_host' at usb-0000:00:14.0-2, RNDIS device, 6a:28:cd:07:4f:f1 usbcore: registered new interface driver rndis_host Then running 'ip link' from a command-line shows I've gained and ethernet device called 'usb0' which I can select in Network Manager if I choose. I suspect your Linkzone device is effectively an Android phone without a screen. But this doesn't help you, because you can't tell your device what USB protocol to select, unless the App for controlling the device that Alcatel's web site mentions lets you do that. There again, if you had an phone to run the app you wouldn't need the Linkzone, you could just use your phone for mobile internet access. Perhaps more relevantly, a previous phone of mine would always show up first as a USB mass storage device, and the contents looked like some Windows software (presumable so a Windows could automatically install something). If I remember correctly. I would have to unmount that before I could connect to it properly for file transfer via MTP or as a USB network device. -- Tixy
