Support Teensy boards
This seems like a complete corner case, but I was encouraged by @akitouni to file this
I'd like my Dirtywave M8 supported in Gnome OS. The device works great as an audio device (audio + midi). The only thing that doesn't work is the remote display functionality that is great for screencasting. I use this tool to capture it on Linux. Also I use the tytools to flash the device firmware. It exposes a /dev/ttyACM0 device usually, or /dev/rawsomething during the flashing process.
Attached are a few device descriptors I created on Fedora Silverblue, where I have been successful using it under toolbx.
