参见图 3， 本发明步骤包含下列步骤：  Referring to Figure 3, the steps of the present invention comprise the following steps:
S10: 提供与储存模块 14连接的 USB模块 12连接主机端 30。 在此， 主机端 30具有与 USB模块 12相对应的连接模块。 USB模块 12 可为 USBl.x、 USB2.0或 USB3.0版本， 其态样可为标准 USB、 mini USB或 micro USB 前述说明中关于 USB模块 12的版本及态样仅为举例， 本发明不 限于此。 储存模块 14可为闪存、 只读存储器或随机存取内存。 S10: The USB module 12 connected to the storage module 14 is connected to the host end 30. Here, the host terminal 30 has a connection module corresponding to the USB module 12. The USB module 12 can be a USB1.x, USB2.0 or USB3.0 version, and the aspect thereof can be a standard USB, mini USB or micro USB. The version and the aspect of the USB module 12 in the foregoing description are merely examples, and the present invention does not Limited to this. The storage module 14 can be a flash memory, a read only memory, or a random access memory.
S20: 以储存在储存模块 14的驱动程序 20驱动 USB模块 12进行传输。 在此， USB模块 12连接主机端 30时， 自动启动驱动程序 20， 驱动 USB 模块 12与主机端 30间进行传输。  S20: The USB module 12 is driven by the driver 20 stored in the storage module 14 for transmission. Here, when the USB module 12 is connected to the host terminal 30, the driver 20 is automatically started to drive the USB module 12 and the host terminal 30 for transmission.
S30:以储存在储存模块 14的监控程序 22监控 USB模块 12与主机端 30 的传输过程是否中断。  S30: Monitor whether the transmission process of the USB module 12 and the host terminal 30 is interrupted by the monitoring program 22 stored in the storage module 14.
在此， 传输过程中断为 USB模块与主机端间的命令传输 （CBW)、 数据 传输、 状态传输 （CSW) 与 ACK封包超时 （Time out) 的情形。  Here, the transmission process is interrupted by command transmission (CBW), data transmission, state transmission (CSW), and ACK packet timeout between the USB module and the host.
由于 USB传输可分为命令传输 （CBW)、 数据传输与状态传输 （CSW) 三个传输阶段。 因此， 在传输过程中监控 USB模块传输是否中断的步骤可为 检查 USB模块 12与主机端 30间的命令传输（CBW)过程、 数据传输过程与 状态传输 （CSW) 过程是否完整， 以判断传输过程是否中断。 因 USB传输过 程中， 数据接收端会传送 ACK封包至数据发送端， 以确认传输是否完成。 因 此在传输过程中监控 USB模块 12传输是否中断的步骤也可为确认 USB模块 12与主机端 30发出的 ACK封包是否正常， 以判断传输过程是否中断。  Since USB transmission can be divided into three transmission stages: command transmission (CBW), data transmission and status transmission (CSW). Therefore, the step of monitoring whether the USB module transmission is interrupted during the transmission may be to check whether the command transmission (CBW) process, the data transmission process and the state transfer (CSW) process between the USB module 12 and the host terminal 30 are complete, to determine the transmission process. Whether it is interrupted. During the USB transmission process, the data receiver transmits an ACK packet to the data transmitter to confirm whether the transmission is completed. Therefore, the step of monitoring whether the transmission of the USB module 12 is interrupted during the transmission may also be to confirm whether the ACK packet sent by the USB module 12 and the host terminal 30 is normal, to determine whether the transmission process is interrupted.
S40: 在传输过程中断时， 以监控程序 22初始化驱动程序 20。  S40: The driver 20 is initialized by the monitoring program 22 when the transmission process is interrupted.
在此， 当检测模块 222依步骤 S30检测到传输中断的情形时， 恢复模块 Here, when the detecting module 222 detects the transmission interruption in step S30, the recovery module
224初始化驱动程序 20， 并重新建立 USB模块 12与主机端 30间的传输， 实 现传输异中断自动恢复传输。 The 224 initializes the driver 20, and re-establishes the transmission between the USB module 12 and the host terminal 30, realizing the transmission of the interrupt automatic recovery transmission.
