could not insert 'g_ether': No such device

Hi,

I’m trying to make Ubuntu 16.04.2 with TI v4.4.x: Real-Time kernel work. I’m stuck with a problem to configure ethernet over USB. I’m doing everything as explained here: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-usbgadget but when I run the beaglebone-black-g-ether-load.sh script, I get modprobe: ERROR: could not insert ‘g_ether’: No such device…

Here is my dmesg: https://pastebin.com/KWBgdTTm
Here is my lsmod: https://pastebin.com/vr7J6QHA

I’ve been facing similar problem before, when I’ve been setting up 4.4 non-rt kernel, and up then solution to my problem was this script added to rc.local: https://pastebin.com/s7K8Kjrf

This time it doesn’t help though…

I’ll appreciate any help.

Regards
Igor

usb based ethernet is already runnin:

Why isn’t this connection working then? Network manager in my host Ubuntu shows it’s still connecting. On the list of connections I already have my BBB, I can ping it, but when i try to ssh to it, I get no route to host error…

Here is an image of my networks list: http://imgur.com/a/GUQck

ssh debian@192.168.7.2

If that doesn’t work…

sudo ifconfig -a

As I manetioned above - I’ve got Ubuntu image, not debian.

Command ubuntu@192.168.7.2 returns “No route to host”

ifconfig -a

Yeah your right for Ubuntu…

Try

sudo dhclient eth1

To see if you can get a proper ip from the beagle.

Thanks for this solution - after running dhclient eth1 that interface got a proper IP address and I was able to connect through ssh with BBB.

I don’t consider this a final solution though, as this involves too much uncertainity and manual work in order to simply connect with the device (especially as this can happen automatically). Unfortunately I don’t feel myself to be that strong in networking topics to be able to find a final solution myself. So thanks for that one, but could you tell me what else can I do?

Regards

@Robert - I did everything as you described here: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-usbgadget

Why do I have two USB interfaces showing up (USB0 and USB1)? If I cannot load g_ether because u_ether is already loaded, do I need to run beaglebone-black-g-ether-load.sh during every boot?

Regards

The two interfaces are normal for all images linked from my elinux.org pages:

http://elinux.org/BeagleBoardUbuntu

On the eewiki.net page i haven't migrated things to the dual usb option yet.. *

This usb option, allows both Microsoft (7, 8.x, 10) to automatly
install a built-in usb-networking driver without our signed driver..
the "other" inteface also works with a built-in MacOSX driver..

It's just linux that see's both interfaces...

Thanks for the info.

Now, even when I run dhclient eth1 I cannot get IP assigned… Like I said, it’s lottery…

So it doesn’t work and I don’t know why… Great…
