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 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 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.
