Ubuntu 17.04. install driver for USB Ethernet Adapter [closed]

Need to install a USB Ethernet Adapter (lsusb string below)

Bus 003 Device 005: ID 0bda:8152 Realtek Semiconductor Corp.

I have got four files by the manufacturer:

/home/sergey/Downloads/RTL8152/LINUX Andriod/50-usb-realtek-net.rules /home/sergey/Downloads/RTL8152/LINUX Andriod/compatibility.h /home/sergey/Downloads/RTL8152/LINUX Andriod/Makefile /home/sergey/Downloads/RTL8152/LINUX Andriod/r8152.c

Q1: Do I need to install these files above somehow?

Q2: If Q1 is negative, How to check the Adapter / make it work?

Note: The main goal is to connect a Wi-Fi hub (Zyxell KEENETIC) via the above Adapter. Indication on the hub shows no network connection via the Adapter.

Please advise. SK

Suppose I used the wrong Interface. Please advise.

A1: No, you needn't install the driver. It is already included in Ubuntu 17.04. It is r8152. From the module aliases:

filename:       /lib/modules/4.10.0-28-generic/kernel/drivers/net/usb/r8152.ko
version:        v1.08.8

<snip>

A2: Insert the device. Check to see if the driver loaded:

lsmod | grep r8152

Check to see if an interface is created:

ifconfig

Check to see if there are any clues in the log:

dmesg | grep r8152
dmesg | grep <interface_you_found>

For example, ifconfig says that my ethernet interface is enp0s25. Therefore, looking for clues, I'd check:

dmesg | grep enp0s25

Post your findings in an edit to your question and I will edit this answer to add troubleshooting steps.
