The correct transfer loop in stm32_usb_interrupt() dispatched every completion to stm32_epdone(), including those for endpoint 0. stm32_epdone() implements the generic bulk/interrupt endpoint completion path. It does not decode the SETUP stage, does not maintain the EP0 state machine, and does not apply the EP0 specific RX/TX status rules. Control transfers therefore never completed correctly and the device could not be enumerated. Dispatch endpoint 0 to stm32_ep0done(), which is the control endpoint handler and is already used for the same purpose by the low priority transfer path in stm32_lptransfer().
