CY_USBFS_DEV_ENDPOINT_TRANSFER_ERROR

An error occurred during a USB transfer.

For an IN transaction, this indicates a “no response” from the HOST scenario. For an OUT transaction, this represents a “PID or CRC error” or the bit-stuff error scenario.

CY_USBFS_DEV_ENDPOINT_SAME_DATA_TOGGLE

The data toggle bit remains the same.

The received OUT packet has the same data toggle bit that the previous packet had. This indicates that the Host retransmitted the packet.
