* Fix compile archive arguments for the new toolchain * Add menu to S2 for picking through which port to upload Internal USB CDC requires to reset and wait for the new port (because persistence is not yet stable) * USB CDC should also be started in main * Fix URL and USB version for WebUSB * Update vendor callback API * Update CDC::write to use TX_DONE semaphore * Update USB_Serial example
