I am able to use both my tinySA and my tinySA Ultra with Linux Mint 20.3 Cinnamon and tinySA-saver 0.2.2.? Are you using the latest version of tinySA-saver from github?
I have heard some have had problems connecting with USB3, but USB2 works OK.? If you have problems with one, you might try the other.? Try hitting the rescan button if saver doesn't see your tinySA.
I hadn't used tinySA-saver in some time and just installed the latest version recently when I got the Ultra.? I used
git clone https://github.com/erikkaashoek/tinySA-saver
in a terminal to download, then used cd to switch to the newly created folder and followed the directions for Ubuntu in the README.MD file, except that I just used python3 where the instructions specified python3.7 since Mint 20.3 is using python 3.8.10 and will use that automatically when given the command python3.? Python3 and pip were already installed, so I ignored that part of the instructions to install those.
