I can connect my Linux device (an embedded device) to a tablet in the following way:

  1. Use a micro USB to Ethernet cable converter
  2. use a USB to Ethernet on my Linux device.
  3. connect the two device to each other via Ethernet

But it is a bit ugly. Is there any way that I connect the two device via USB and then use IP communication to communicate between the two device?

The table runs Android and the device runs Ubuntu.

The reason that I want to do this is follow:

I have a web server on my embedded system and I want to allow users to connect to it using a USB cable and use a browser to change parameters on embedded device.

Lets see what the kernel configs looks like:

cat /boot/config-$(uname -r) | grep  CONFIG_USB_ETH

Output:

bob@bob-NE722:~/Downloads/odoo-8.0$ cat /boot/config-$(uname -r) | grep CONFIG_USB_ETH
CONFIG_USB_ETH=m
CONFIG_USB_ETH_RNDIS=y
CONFIG_USB_ETH_EEM=y

This indicates that compiled into the ubuntu kernel is support for RNDIS and EEM, but usb ethernet emulation has to be loaded as a module.

Lets see if g_ether is included:

bob@bob-NE722:~/Downloads/odoo-8.0$ locate g_ether
/lib/modules/3.16.0-23-generic/kernel/drivers/usb/gadget/g_ether.ko
/lib/modules/3.16.0-29-generic/kernel/drivers/usb/gadget/g_ether.ko

And then:

sudo modprobe g_ether

And configure the usb ip address:

ifconfig usb# 192.168.0.#

And enable on boot:

echo g_ether > /etc/modules-load.d/g_ether.conf

And on the android device:

There should be a setting to enable usb tethering.

  • And on the tablet-side enable reverse tethering or something similar? – Nils Jan 24 '15 at 22:40
  • @Nils I haven't used a lot of android devices, but I thought there was a setting to enable usb tethering? Settings --> Wireless & Networks --> Internet tethering or Tethering & Hotspots See: wiki.archlinux.org/index.php/android_tethering#USB_tethering – jmunsch Jan 24 '15 at 23:15
  • You should add that note to your answer. I am not sure wether tethering will do work as expected in this constellaton, but it might work. – Nils Jan 25 '15 at 21:51
