Don't get IP by USB direct connection

Hi

I have a PC with Windows 7 without administrator password. So I'm using an Oracle VirtualBox VM with newest Ubuntu. I am able to activate USB forwarding for the Udoo, and the Ubuntu is creating a new interface for the udoo. But it doesn't get an IP address (192.168.7.1).

I'm further able to connect to the udoo by using minicom...

How can I reset the IP configuration? dhclient doesn't work. How is the IP configuration handled?
Thank you for any hints!

 

I found the solution to set the IP address (192.168.7.1) manually. It worked for me for the moment.

 

@szhvoj, I found that setting a wider range of IP in interfaces and dhcp makes everything faster and more reliable.

So /etc/network/interfaces:

Code:

[...]
# USB OTG connection
allow-hotplug usb0
iface usb0 inet static
address 192.168.7.2
netmask 255.255.255.0
[...]

and /etc/dhcp/dhcpd.conf

Code:

[...]
subnet 192.168.7.0 netmask 255.255.255.0 {
  option routers    192.168.7.2;
  option subnet-mask  255.255.255.0;
  range 192.168.7.1  192.168.7.100;
}
