So I bought an USB to Ethernet adapter. It also has two more USB 3 ports. When connected on my laptop, I'm unable to acquire an IP through my DHCP, but a new network interface is automatically raised. I tried to set manually an IP, but I cannot ping any system which normally honors ping requests. The surprising point is that when I connect the same adapter on an old laptop (Dell E4300), running the same version of Ubuntu 14.04 (both systems are fully up-to-date), it perfectly works ! The only difference I can see is that my old laptop has only USB 2 ports... Additionally, the USB hub works on both computers, and I connected the adapter to 2 desktop computers : - one with an additional USB 3 card : it works ; - one with embedded USB 3 port : same error as with the modern laptop. So it really seems to be a problem related to the way USB 3 is handled by Ubuntu 14.04, but perhaps only with some specific chipsets. I cannot find what chipset is on the mainboard of my laptop (it is an Intel one, for sure, since the CPU is a Core i5-4210Y), but my desktop PC as an Intel Z97 chipset. Here is what I read tailing kern.log when connecting the adapter.
