Failed to bring up usb0

Hello all,
My usb0 interface has suddenly stopped working and will not start properly.

Things were working well but after a power-off and reboot via SW2, usb0 no longer comes up.
Luckily I have a serial port adapter attached to the BBB J1. Otherwise I would be dead since I can no longer ssh into BBB from the host pc.

I am running the latest Debian image on a BBB with this kernel:

Linux beaglebone 4.4.52-bone16 #1 Tue Feb 28 06:56:05 UTC 2017 armv7l GNU/Linux

ifconfig usb shows:

usb0 Link encap:Ethernet HWaddr d0:5f:b8:d2:78:b6
inet addr: Bcast: Mask:
inet6 addr: fe80::d25f:b8ff:fed2:78b6/64 Scope:Link

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

Note that there are NO RX/TX packets. This is the first clue.

/etc/network/interfaces contains:

Ethernet/RNDIS gadget (g_ether)

Used by: /opt/scripts/boot/

auto usb0
iface usb0 inet static

Taking usb0 down gets:

debian@beaglebone:~$ sudo ifdown usb0
ifdown: interface usb0 not configured

Restarting networking gets:

debian@beaglebone:~$ sudo /etc/init.d/networking restart
Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
See “systemctl status networking.service” and “journalctl -xe” for details.

and systemctl status networking.service shows:

debian@beaglebone:~$ systemctl status networking.service

The message “Failed to start Raise network interfaces” is seen as boot messages scroll by on the console.

Any help would be greatly appreciated!!!

Fixed. Turned out to be an issue on the host PC.

Do you remember how you fixed this?


it’s been a while, but I think the issue was resolved with a reboot of the host, which is a macbook. I may have updated OSX as well.
Good luck!
