Pro Trinket not detected by Windows 10

I was able to program my Pro Trinket exactly once with the Blink example file. However, now Windows does not even detect the device and when I reset, #13 flashes 2 times and then starts running Blink again

Did anything occur during programming? A power fluctuation, accidental disconnect, anything like that? That kind if thing can cause corruption to the bootloader.
If you have an Arduino Uno or equivalent, you can repair the bootloader:

The problem could also be something as simple as a dodgy USB cable. It's worth trying some different ones.

It went through several erratic behaviors before suddenly working properly again. I have no idea why. Maybe there was some water on it ¯\_(ツ)_/¯
