USB调试经验

1、USB调试经验时间:2007-08-16来源:作者:点击：4589字体大小:【大中小】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bushound抓总线小样时才发现的。bushound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bushound！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，bushound抓的。别的设备类也有通用性BusHound5.00capture.Complementsof中国电信优盘作者注：20.0是指主设备号20,子设备0。其实就是说20是usbhub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-DeviceID(followedbytheendpointforUSBdevices)(20)USBMassStora。
