 |
|
Is there a Linux driver to connect an Android phone (Samsung Galaxy S4) as a networking interface, using the mobile network on the phone as a route to the Internet? I've done this using WiFi, but is it possible over USB?

Of course. Check this:
http://wiki.gentoo.org/wiki/Android_USB_Tethering
EDIT: as a related note, connman (and the connman-gnome frontend) works nicely as long as your kernel is able to detect and configure the device. It will list your usb connection as a wired network. So, if you use that you don't have to mess at all with udev rules or network configuration at all. I don't know about networkmanager and other similar tools. |

| Hi, I am curious if you can get it to work or if you had problems. |

dhcpcd, and the dhcpcd-gtk and dhcpcd-qt front ends also work fine.

I can't seem to get any usb networking devices:

dmesg will show

But no usb networking devices:

I don't know if the UNRECOGNIZED entries will show up on a working interface... |

The problem maybe lies in (Samsung Galaxy S4) software version or the settings.
The reason why I use a google nexus 4 is in custom firmware and all available software options.
Your carrier or your smartphone itself blocked this service or made it unavailable. As I do not have such a device it is just a guess.
Maybe you can connect with the android debug bridge and dig around in your phone but I would have to look up myself what you can do with adb. Therefore it is just a hint and I have never done it before. As said it depends on your software of the phone and what is locked or made unavailable.
as the gentoo wiki notes some devices which works and I assume you did all what the gentoo wiki says it has to be your phone than itself. |

I haven't an s4 to test (my phones are much cheaper  ) but I think that phone should just work.
So, are you enabling usb tethering in the phone? You have to do that, otherwise all your computer will see is a storage device (if anything). It's usually in the same place where you enable the wifi access point.
Also, try enabling this:
| Code: | | # CONFIG_USB_NET_RNDIS_WLAN is not set |
I don't know about the s4, but my dg350 certainly needs it. |

As I mentioned I've done it in the past using the WiFi interface rather than USB so the phone and provider should allow this to some extent.
I've been using adb for Android development, but I can't see how it can help me here as many of the typical command are generally disabled/different. The proc filesystem is there, but I don't know what I should check...
| Code: | $ cat /proc/version

Yes I have enabled the USB Internet sharing. If I don't lsusb will only show information about camera and serial communication:
| Code: | bInterfaceClass 6 Imaging
bInterfaceSubClass 1 Still Image Capture
bInterfaceProtocol 1 Picture Transfer Protocol (PIMA 15470)
iInterface 5 MTP
...
bInterfaceClass 2 Communications
bInterfaceSubClass 2 Abstract (modem)
bInterfaceProtocol 1 AT-commands (v.25ter)
iInterface 6 CDC Abstract Control Model (ACM)
|
Nothing about "RNDIS Communications Control" and such as I listed above.
I don't know how to enable CONFIG_USB_NET_RNDIS_WLAN. The option listed in the Wiki results in CONFIG_USB_NET_RNDIS_HOST getting set. |

| Seems like a kernel update (3.14.14-gentoo) did it. At least now I see a enp0s20u3u2 when running ifconfig, and it has been assigned an IP address |

Oh, forget about that, I mixed up the two RNDIS options, your config should be fine in that regard.
At least for me, the modules are autoloaded when I have the phone connected and I enable the usb tethering option. If that doesn't happen in your case, then it could be because there's no right module for your phone. I would try enabling everything under device drivers->network dev support->usb adapters as module 'M'.
If that doesn't work, double check that you haven't blacklisted anything related under /etc/modprobe.d/*.
Also, I use "eudev" with USE="gudev hwdb keymap kmod modutils openrc rule-generator", if you use this or udev make sure you have USE=kmod enabled, it probably needs that to autoload modules though I really try to know as little as possible about udev and co.
EDIT: Ups, just saw your update above. I am glad that you made it work. See you around  |
