# Send any Token packet.
SendUsb2TokenPackets();
# Send all SETUP packets.
SendUsb2TokenPackets (PID_SETUP);
# Send all IN tokens for address 5 endpoint 1.
SendUsb2TokenPackets (PID_IN, 3);
# Send all OUT tokens for address 3.
SendUsb2TokenPackets (PID_OUT, 5, 1);
# Send all token packets for endpoint zero.
