Hello,
I made a new gentoo fresh install but got a strange "warning" at boot, somthing about ModemManger and no support for a device. It didn't happen on the previous install. I checked what this device represents, and it looks like its Dell D3100 USB3.0 Dock device.

Yes i use dock station for internet because standart eth0 port is broken, so i use usb ethernet adapter, that comes from dock station as usb0 interface.

I also noticed when i run ifconfig, instead of usb0, eth0 shows up. On the previous install there was only usb0 and wlan0.

Can someone help me with this werid situation, i think its not properly configured.

P.S i have also set this in /etc/default/grub
Code:
GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0"

The warning in terminal:

Please help me, i really don't like that ugly output at the terminal, also i have to actually press enter for login prompt to come up. This is very inconvenient because i use a script that automatically selects the user at login prompt and i have only to type the password.latest?d=yIl2AUoC8zA latest?i=zjFih8YP7vg:tfJIf7heyrc:F7zBnMy latest?i=zjFih8YP7vg:tfJIf7heyrc:V_sGLiP latest?d=qj6IDK7rITs latest?i=zjFih8YP7vg:tfJIf7heyrc:gIN9vFwzjFih8YP7vg
