I need a fully-working firmware for an "Adafruit RP2040 board USB Type-A host" that can sit between a wired gaming mouse and the PC. Its job is to spoof the original mouse’s VID, PID, serial number and any other required descriptor bytes so the operating system believes the orginal mouse is of a different brand. Key behaviour • Gaming mice are the priority, but the solution should fall back gracefully with most common wired models. • All native packets from the mouse must pass straight through untouched, so the user experiences zero latency or feature loss. • At the same time the firmware has to expose its own composite HID interface that lets me inject cursor movement, click events and scroll actions programmatically. Implementation ...

The task is to design a compact PCB that drops straight into an SCX 1/32 car so it can run on a digital track. I want the board to read the track’s reed-sensor signal, let me assign any of 20 unique car IDs in firmware, and expose a surface-mount USB-C port on the edge for easy flashing once the body shell is back on. Size must stay close to the original analogue board footprint (about 24 × 18 mm, height under 6 mm) but I can adapt mounting holes or connector positions if you have a cleaner layout idea. Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry. I haven’t locked the MCU yet; pick anything small, inexpensive, and easy to program—ATmega, STM32, ESP3...
