[gentoo-user] eth over usb

Hi,

I'm installing gentoo on new laptop which doesn't have eth slot. I have 
i-tec usb-eth adapter which works fine (tested on linux live 
distribution).

For the first time: I've configured kernel, compiled, loaded kernel 
module and created link to /etc/init.d/net.lo and somehow I've push it 
all to work (ifconfig lists enp0s20f0u1 interface).

But after reboot plugging in the adapter doesn't create enp0s20f0u1 
interface, so the ifconfig lists only 'lo'.

Please could somebody help?

Attached is kernel config, lshw and dmesg outputs.

Thanks

Pat

Does ifconfig -a list it?

If not, does it show up if you "modprobe r8152"?

Best way to get a handle on what you need for things like this is to
reboot into the live cd and plug in the adapter. Then examine dmesg,
lsmod and othr relevant sources of info to see what the live cd did.
Make notes, replicate that on your gentoo system.

Almost any other method really just comes down to firing in the dark and
hoping you might hit something.

Can you get 100Mbit/s with it?

The laptop I use also has no ethernet.  I bought a USB dongle for that
but it turns out it can only do the original 10Mbit/s, half-duplex; much
slower than wifi and even somewhat slower than the WAN connection here.

Thanks to all for suggestions.

The problem was that I've created net.enp0s20f0u1 and also net.eth0 
links.

Thanks

I have a gigabit USB 3.0 to ethernet adaptor here. It's branded Digitus
which probably means nothing, lsusb shows

The one I have is also USB3 and looks fast, but I didn't test it yet - 
right now trying to setup gentoo :-)

I'm blessed with city operated fiber to premise gigabit ethernet, when they do an install they check with a laptop with a gigabit usb3 adapter.  it actually got about 960Mb/s.
