Hi all,
I have a couple of beagle bone black but I ssh or access the http server or even successfully ping the board when connected through usb (haven’t tried ethernet).
My host machine is an arch linux, first of all, when I connect the board a new network interface appears (enp0s26u1u2):
The state is down and it has no IPv4 address assigned
If I set it to up: $ ip link set up dev enp0s26u1u2 the state switches to UNKNOWN:
`
$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s25: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether f0:de:f1:d9:7d:29 brd ff:ff:ff:ff:ff:ff
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
link/ether 10:0b:a9:c0:87:d4 brd ff:ff:ff:ff:ff:ff
inet 192.168.100.67/24 brd 192.168.100.255 scope global wlp3s0
valid_lft forever preferred_lft forever
inet6 fe80::120b:a9ff:fec0:87d4/64 scope link
valid_lft forever preferred_lft forever
13: enp0s26u1u2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
link/ether 90:59:af:54:03:1f brd ff:ff:ff:ff:ff:ff
inet6 fe80::9259:afff:fe54:31f/64 scope link
valid_lft forever preferred_lft forever
`
And ping to 192.168.7.2 fails
The mass storage mounts alright but if I follow the link to the board http server I get no response.
Another thing I’ve noticed different from the guide is that there is a new device file in /dev: /dev/ttyACM0
but /etc/ttyUSB1 and /etc/ttyUSB2 are not present.
I am dying to try the board but I can’t even connect to it 
Help much appreciated.
