According to the datasheet, this driver should clear the INTSTS0.CTRT bit before this controller detects the next stage transition. Otherwise, the driver may not be able to clear the bit after the controller went to the next stage transition. After that, the driver will not be able to clear the INTSTS0.VALID, and a usb control transfer will not finish finally. If we use the testusb tool, it is easy to reproduce this issue: # testusb -a -t 10 Since the previous code handled a data stage and a status stage in the usbhsf_pio_try_push(), it may not clear the INTSTS0.CTRT at the right timing. So, this patch change the timing of usbhs_dcp_control_transfer_done() to the usbhsg_irq_ctrl_stage().
