Welcome!
I have a 900MB USB, and of its small storage room, i don't use it.
Today i wanted to do something with it and really use it for something.
-----------------Some time later...-------------
I tested the Disc with the DS Linux on my main computer, and on a VM.
But, on the computer and VM, the mouse wasn't moving. I tried searching for solutions, and i didn't found anything. I'm not a so big expert in Linux, i know some basic commands, but i'm not so good to troubleshoot a mouse on a so limited-features Linux.

Ask me if you need some more information, any help is appreciated!

Not sure why the mouse wasn't working when using DSL as a guest in a VM. With a VM the host provides a generic virtual mouse device to the guest, so as long as the host supports the pointing device I would expect it to work in guest as well.

Input devices can be enumerated via
If the mouse is not identified with the above (when running DSL natively) then it is likely the underlying kernel support is not there.

Hmm... Didn't work.

Which VM are you using?
