I am trying to install the wifi adapter for the Mercusys mw300uh.

lbusb output:

I had same issue with Mercusys(rtl8192eu) as you. I found the solution here:

https://github.com/Mange/rtl8192eu-linux-driver

Before you start, I recommend removing the current driver, with the following commands:

$ sudo rmmod 8192eu
$ sudo rmmod rtl8xxxu
$ sudo dkms remove rtl8192eu/1.0 --all

I know this thread is very old, but anybody facing similar issues with WiFi adapter, to the beginners in Ubuntu such as myself, please follow this:

lsusb

  1. This will list all usb connected devices, find your usb in the list, usually has 802.11, Wireless, etc. written on it.

  2. Identify its PID/VID, will be something like 0bda:c811, search this on the web and you should find its chipset (or if you're lucky enough, like I was, you'll find another article or solution that will guide you correctly in installing your respective driver).

  3. Say you're not lucky enough, then you just google that chipset and search for driver ubuntu. Ez pz. Took me 2 days to figure it out and had to struggle with a 2GHz adapter until then :'( Peace!

Note: You will have to disable Secure Boot in BIOS, usually clicking F2 on Startup takes you there, then find Boot related section and disable Secure Boot. And you have to reboot for it to work.
