d12枚举请教,用bushound看不到主机发送了getdescriptor,而电脑要求装驱动,我做的是优盘,设备,端点,接口描述符应该没问题

我的D12是有测试程序的,几乎不用改变配置.我用来做一个优盘,设备,端点,接口描述符等和我原来做的优盘几乎相同(已经成功),只不过这次用了D12的.我把用Bus Hound抓的数据给大家看一下.希望能得到各位大哥的帮助.

然后windows2000叫装驱动,实际上在windows2000下,优盘不用驱动.用了一台windows XP的笔记本,问题也一样.最重要的是,说明这是MassStorage设备的描述符,根本没有发上去.我将和我原来抓的我做的优盘数据对比,在以上数据的基础上,主机对发现的新设备继续发送3次get descriptor并进行进一步的枚举.
