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

Note that there are NO RX/TX packets. This is the first clue.
/etc/network/interfaces contains:

auto usb0

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:

The message "*Failed to start Raise network interfaces*" is seen as boot

Any help would be greatly appreciated!!!
