      @nedos GPIO header might allow room for an add-on though.

      @AndreaBarisani I know. But I just like the idea of “authorizing” the access with a physical button press on the USB peripheral

      @cynicalsecurity you need a button first :D and then you use GPIO. It’s a nice feature in some scenarios /cc: @AndreaBarisani

      @nedos what I meant is "how do you know GPIO isn't lying?", serious question /cc @andreabarisani

      @cynicalsecurity the issue I’m concerned with is host-side, you don’t fully trust the host. Not hardware tampering /cc: @AndreaBarisani

      @nedos @cynicalsecurity one of our concepts is authenticating the host, we can shut down independently if we don't like it

      @AndreaBarisani @cynicalsecurity haha you mean the usb HID shutdown or USB disconnect and endless loop. Both are epic solutions :)
