Adafruit Pro Trinket Bootloader
This is the code for the Pro Trinket bootloader. There are two versions, HV (16MHz 5V) and LV (12MHz 3V), adjust Makefile and recompile.
Check the Makefile for fuses, etc. For advanced users only - we do not offer any support for this code!
Please note: you cannot use the Adafruit USB VID/PID for your own non-Trinket products or projects. Purchase a USB VID for yourself at http://www.usb.org/developers/vendor/

This code is heavily derived from USBaspLoader, but also from USBtiny, with USBtinyISP's settings
