+TinyUSB is an open-source cross-platform USB Host/Device stack for embedded systems. It’s designed for memory safety
+(no dynamic allocation) and thread safety (all interrupts deferred to non-ISR task functions). The stack emphasizes portability,
+small footprint, and real-time performance across 50+ MCU families.
