So you need a host (one that you physically plug the usb device in) and a client (where you share the device to)

on the host you install the server software
Go to The github page and download the correct package for your hardware

sudo apt install qusbipserver_<arch>.deb

where arch is the architecture of your host (raspberry pi 2 is armhf, rpi 1 is armel, raspberry pi 3 & 4 is usually arm64, and a desktop computer is generally amd64

and on the client (which I only built for intel/amd 64 bit) go to https://github.com/dicetrash/qusbip/releases and load either the debian package if you have debian based distro (like ubuntu) or arch.  You should generally be familiar with your package manager
so

sudo pacman -U qusbip.pkg.tar.gz
on arch based and
sudo apt install ./qusbip.deb
on debian based distros

for debian based I start the service for you
for arch then run sudo systemctl start qusbipserver
