36.8.3 Endpoint 1-7 RX Count Registers
RXCOUNT is a read-only register that holds the number of data bytes in the packet currently in line to be read from the RXFIFO. If the packet was transmitted as multiple bulk packets, the number given will be for the combined packet.
Note: The value returned changes as the FIFO is unloaded and is only valid while
RXPKTRDY (RXCSR.D0) is set.
