在枚举usb设备时，在SetConfiguration后一定不要忘了SetInterface，没走这一步80%的设备认不了（我做读优盘时就因为忘了它元旦好几天都没过好）。这一点很多51+SL811的例程都忘了。我也是后来用bus hound抓总线小样时才发现的。bus hound真是颗救命稻草，建议所有调usb的朋友，开门四件事：看《usb2.0原理与工程开发》前六章；下载例程；看要做器件所属usb设备类的说明；学会用bus hound！这四件事都做好再开始，福神才会最大地保佑你。
下面是win2000认优盘时总线上的活动记录，bus hound抓的。别的设备类也有通用性

作者注：
20.0是指主设备号20,子设备0。其实就是说20是usb hub的一个口，0是0号端点
24是初步认出usb设备后分配的设备号
Device - Device ID (followed by the endpoint for USB devices)

作者注：到此为止是枚举usb设备已完成
作者注：win2000没有设置usb地址，亦没有Get Interface，但这两步朋友们可以因自己的应用添加，没关系的
作者注：因为插的是优盘，win2k开始使用scsi-2命令枚举海存设备，比如inquiry, read capacity等，不做优盘的朋友可以不看
