USB interface for PC communication procedures, could be the next-bit machine USB interface data transmission to the PC machine and processed. Each data transmission are PC initiative, the first host computer to send the command (to borrow DEMO program version number part), the next-bit machine READ_VERSION received orders on the transmission of 64 bytes of data to the host computer, and start running, each time I send to Send frames plus 1, the time and number of frames sent to the host computer for easy observation upper 64 bytes of data received on the given machine to send the next bit READ_VERSION command, repeat 1000 times, test takes about 31 seconds. 64-byte: the first 2,3-byte frame is sent, 61 bytes is the communication time (S)
