请大家帮忙--AN2131QC 芯片的应用

我用 AN2131QC 芯片做了两个设备, 设备的硬件电路完全相同, 但是它们的固件和 EEPROM的内容不同。 我为每个设备分别写了INF 文件和固件下载驱动程序文件。 但是两个设备插入同一主机时总是下载相同的固件,而变成了同样的设备。请问如何解决？是不是INF 文件写得不对，我是根据EZUSBW2K.INF改写的，INF 文件编写规范哪里能得到?
敬请高手指点。
  上述两设备的 EEPROM值分别是 B0 47 05 60 10 01 00 和 B0 47 05 00 60 01 00 。固件 VID/ PID 分别的是 0x547/0x1061 和 0x547/0x6001。我用的操作系统是Windows 2000 Professional。
两个 INF 文件在附件中。

 上述两设备的 EEPROM值分别是 B0 47 05 60 10 01 00 和 B0 47 05 00 60 01 00 。固件 VID/ PID 分别的是 0x547/0x1061 和 0x547/0x6001。我用的操作系统是Windows 2000 Professional。

********************************************
EEPROM值应为B0 47 05 60 10 01 00和B0 47 05 01 60 01 00

估计没有读出EEPROM里的内容来，都用了默认PID VID
