f2812与isp1581连接，问枚举问题
请问老师
我用DSP连1581，16位通用总线模式（参考的是手头一块51控制1581的开发板，8位复用模式）。 如今 HS_STATE 中断完成后，做什么？ 什么时候出现第一个EP0SETUP中断 zhangdeyuan@126.com |

你好，我现在也在做 isp1581+FPGA 开发一个 USB 系统，我和你的问题差不多，我是这样处理的：进入高速状态检测后，我将测试方式寄存器（84H）中的FORCEHS和PRBS都置1，
处之后就进入了EPO SETUP中断，读EPO SETUP缓冲区我发现收到的请求是获取设备描述符的请求，我将我的设备描述符（18个字节）发过去后就没有反应了，一直停在EPO SETUP中断，不知道怎么处理，还望各位大牛指点迷津，谢谢了。 |

描述符错了吧

谢谢 jinghuiren 大哥的指点，谢谢了。
我怎么才能够判断我的描述符是否正确？我将发送的描述符同时输出了，是正确的啊 用 bushound 抓到的只有主机一直发送的 get status 命令，不知道究竟是怎么回事。 我还想请教大哥一个问题，怎样检测我发出的数据是主机没有收到还是发送的描述符错误？ |

如果发送正确bushound应该能收到你发送的描述符
或者是你把数据填到端点里了，但是你没有使端点生效 你可以先将要发送的数据数量写入datacount寄存器，然后再往端点里填充数据，数据够了后 端点会自动生效发送给主机 |

谢谢jinghuiren大牛的指点
我按照你说的做了，把发送的数据数量写入datacount寄存器，还是没有收到主机的其他命令 而且我在 bus hound 上没有看到我发送的描述符，也没有抓到主机发送的 get descriptor 但我通过 signalTap(在线调试,FPGA 的一种调试方法)看到主机给我的 SETUP 包的内容确实是获取描述符的请求(80 06 00 01 00 00 40 00) 接着我按照 isp1581 的编程指南上的顺序做了以下几步： 1 访问索引端点寄存器(2CH) ,选择控制端点输入 2 将我的设备描述符( 18 个字节) 写入数据端口寄存器， 3 接着使能输入控制端点的缓冲区(这里 STATUS 位需要置 1 吗?) 4 等待 EP0 IN 中断 ，中断来了以后访问索引端点寄存器，选择输出控制端点，置 STATUS 位(这里需要将控制端点输出的缓冲区使能或清除吗?) 5 等待 EP0 OUT 中断，中断来了之后结束。 我按照以上过程做了以后，发现主机发给我的命令还是 80 06 00 01 00 00 40 00 ，而且我发现程序进入过 EP0 IN 中断，之后就又进入了 SETUP 中断 ，始终进不了 SET ADDRESS 或其它请求状态， 我还有一个问题是我在高速状态中断中将 测试方式寄存器(84H)中的FORCEHS和PRBS都置1 了，要是不这样做的话就始终进不了SETUP 中断，请问这正常吗? |

jinghuiren 大牛 我还有一个问题要请教
为什么我用 bus hound 抓数据时，电脑总是会重启 ，只有当我把 bus hound 切换到 Device 标题栏下 ，当程序运行后再切换到 capture 下才不会重启 我用 bus hound 抓到的数据如下 Bus Hound 5.00 capture.

谢谢两位大哥的指点.现在我已经将问题解决了.
原来在windows xp 下只有当枚举完成后才可以看到枚举的前几个步骤,所以我又重装了windows 2000系统,可以看到枚举没有成功时的几个步骤. |

求助: isp1581 上传数据至主机
各位大牛好,小弟用 isp1581 开发 USB 时遇到这样一个问题: 主机能够正确枚举设备,主机往设备传数据已经 实现了,但是若要将数据上传至主机该如何处理? |
