Verilog and Python for decoding USB Keyboard and USB Mouse streams from ch559 module MatzElectronics has this neat $10 module that has 2 USB ports and outputs a UART data stream at 400,000 baud (3.3V). https://www.tindie.com/products/matzelectronics/ch559-usb-host-to-uart-bridge-module/
This repository has a Python script (usb.py) which decodes Keyboard and Mouse streams via a FTDI TTL-232R-3V3 cable.
Using information captured from this, a verilog decoder was created which then outputs 16bit data for keyboard events and 32bit data for mouse events.
Note that Gamecontroller decoding wasn't successful. The gamecontrollers that were tested output a continous stream of data which most likely overruns the 400,000 baud UART on the ch559 module.
