 Obviously you can also build your own firmware. To build the *standard* one I used:
 
 - Arduino IDE `2.2.1`
-- `Adafruit TinyUSB Library` version `2.2.3`, Board `Raspberry Pi RP2040 (3.6.0)` setting Tools=>CPU Speed at `120MHz` and Tools=>USB Stack to `Adafruit TinyUSB`
+- `Adafruit TinyUSB Library` version `2.2.5`, Board `Raspberry Pi RP2040 (3.6.0)` setting Tools=>CPU Speed at `120MHz` and Tools=>USB Stack to `Adafruit TinyUSB`
 - `ssd1306` OLED library version `1.8.3`
 
 If you want to re-create a new fake filesystem, you may want to have a look to the `utils` folder, where I placed some utilities to build a new one.
