EEPROM已经有头绪，却得不到pipe信息，WHY？

在EEPROM missing的情况下，我用USBCheck测了一下，我的板子全部通过测试，也得到Device 00 Vid(0x0547) Pid(0x2131)，估计EEPROM没问题了。我用开发板的控制面板随便下了一个固件（例如bulk test），却得不到Endpoint和pipe等信息，为什么？我也不知道板子是否工作，怎么办？

我今天下午在24LC256里写了用USBCheck得到的信息：B0 47 05 31 21 01 00，结果WIN98还是认为EEPROM missing.如果用开发板带的EEPROM信息（B0 47 05 80 00 01 00），WIN98就认为是开发板。请问这是怎么回事？谢谢。

用古怪点的数值就不missing了。

sunkai兄，我换了EEPROM信息，VID（0543），PID（1234），够古怪了吧，然后加上去，完了，WIN98根本不认我的的板子，说是未知的USB设备，还让我安装驱动，请问怎么回事？

很正常，换了个标识当然是新设备了，不问你才是怪事，要改inf，重新安装，以后就认了。原理要搞清楚哦。
