    FX2LP driver confirming

    ClGa_2453791

      Hi Cy:

      CY7C68013  board通过USB连接电脑提示如下信息,请问是驱动的问题导致吗?

       

      同样文档中的“”FX2LP DVK Recognized by USB Control Center “”也无法实现,

       

      还请帮忙指导下该如何操作,谢谢!

          首先,确认下驱动是不是正确安装过?你安装过 FX3 的SDK的话,驱动应该是已经安装好了。

          其次,确认下驱动管理器是报什么类型的错误,是否是 不能成功获取描述符。

          最后,用 BUS HOUND 抓下 枚举阶段的trace。

              你贴的内容是两个不同板子的trace?

                是的,有用分割线区分!

                上面的是异常信息,提示 USTS   80000300        bad parameter

                  你这个属于硬件(或芯片)故障。
