WINCE60下的USB OTG怎么实现啊，CE要加什么组件，USB OTG的驱动要进行怎样的修改？一头雾水！

选择USB Host驱动，然后根据自己的硬件情况进行修改！
看来好难啊！没什么概念！不知道又要痛苦到什么时候。楼上实现了？
uhci(universal host controller interface): Intel用在自家芯片组上的usb 1.1主控制器(host controller)的硬件实例。
ehci(enhanced host controller interface): usb 2.0的主控制器标准接口。
ohci(open host controller inferface)：一个不仅仅是usb用的主控制器接口标准，下面细分为usb，1394，或者更多（别的没有接触过）。主要是遵循csr(configuration space register)标准（另一个标准，呵呵）。是其他厂商在设计usb host controller时遵循的标准，如via, nec, ali, 包括nvidia等等。
uhci, ohci在硬件实现以及对底层软件访问上都有所不同，但二者又都完全（实际上各自多少都有些不足）支持usb 1.1 specification里边对usb host controller的要求。
同理，ehci是满足usb 2.0 specification里面对usb host controller (high speed)的要求的硬件设计。
应该是从win98之后usb1.1就被广泛支持了，无论是uhci还是ohci。但ms真正支持usb2.0（或者说ehci）是从win2k sp4和winxp sp1。这里所说的真正支持是指系统自带ehci的驱动而不需要第三方的驱动程序。
apple现在胳膊拗不过大腿，在mac机上也已经都开始支持usb1.1和2.0接口。而上面的host controller一定是ohci的标准。
WINCE60下的EHCI/OHCI/UCHI这3个只能选择一个!6400BSP里面提供的是s3c6400_ohci2.dll驱动,那不是还是不能支持EHCI吗?也就是不支持USB2.0啊!
