Failed to bring up usb0

[davis.m...@gmail.com]

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:192.168.7.2  Bcast:192.168.7.3  Mask:255.255.255.252

          inet6 addr: fe80::d25f:b8ff:fed2:78b6/64 Scope:Link

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          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/autoconfigure_usb0.sh

auto usb0

iface usb0 inet static

    address 192.168.7.2

    netmask 255.255.255.252

    network 192.168.7.0

    gateway 192.168.7.1

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.

 failed!

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.

Thanks,

Do you remember how you fixed this?

Thanks

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!
