Help with M5 Unit V2 on Linux

aafortinet

Hi,
I've just purchased a M5 Unit V2, and would like to use it on Linux. I read the documentation, but it's mostly for Windows and Mac. I'm using a Linux Debian.
I believe however it's surely possible.

When I plug in the device by USB, I notice a new USB device:

Bus 001 Device 011: ID 0fe6:9900 ICS Advent USB 10/100 LAN

There is also a new network interface, but notice I don't have an IP address on it.

10: enx00e0992fbd3c: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:e0:99:2f:bd:3c brd ff:ff:ff:ff:ff:ff

I tried to do an down/up on that interface but it did not change anything.
I have no 10.254.239.1. I have no idea how to contact my device...

$ ping 10.254.239.1
PING 10.254.239.1 (10.254.239.1) 56(84) bytes of data.
^C
--- 10.254.239.1 ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1012ms

What should I do? What am I doing wrong? Thanks.
