在指定位置找不到硬件信息

    我用driverstudio生成了一个USB的驱动程序（在生成USB驱动程序时我选的是98/2000系统），并且编译通过没有错误生成了一个myusb.sys文件，但当我在98系统接上我的USB硬件，选择从磁盘安装该驱动程序时，系统指示：“在指定位置找不到硬件信息”。我换到2000系统中出现同样的错误，不知道是什么原因，希望各位指点一下！
谢谢！

vid/pid不匹配

我是用USBVIEW这个软件看的呀，然后直接复制填在VID和PID里面的呀

那就不清楚了，把你的inf文件贴出来看看。

这是由driverstudio直接生成的，没有改动的

感谢您的再次指点！

class 应该是usb吧
另外把ClassGUID={ff646f80-8def-11d2-9449-00105a075f6b}
去掉试试
