Wired Connection problem. USB-Ethernet adapter not recognized

  • 772

My computer is ASUS-UX305FA running Ubuntu 18.04. This laptop does not have an Ethernet port, yet it comes with an Ethernet-to-USB adapter. Unfortunately, I played around with network configurations, and now it does not recognize the adapter. I would like to note that my wireless connection is up and working, also the green light on the adapter is blinking. I searched forums for solutions (for 2 weeks) but none worked.

sudo apt-get update
sudo apt-get upgrade

did not solve the problem either.

here is my ifconfig output

~$ ifconfig

Thanks in advance !!!

EDIT ON REQUEST OF heynnema:

~$ lsusb

As you can see, device is not seen.

...so tell us what you did

Sorry, I panicked and tried many things which I had no idea about and I do not remember them

EDIT2

I ran Ubuntu from a live USB and here is the output of lsusb command:

Bus 001 Device 002: ID 0781:5567 SanDisk Corp. Cruzer Blade device is live USB
