is there someone who's mastering teensy keys? I have a question.

I need to understand it these keys could be used in a linux arm distro which doesn't have HMI USB drivers (so it makes no sense to emulate a malevolous keyboard or mouse). The USB keys in the distro I have could only be seen as mass storage, I would therefore understand if these keys could be used to exploit something in that case also..

Thanks in advance!
