【usb 总线枚举失败！ 《usb function driver》问题如何排查！】 [复制链接]

【平台：】 2440+wince5.0
【目的】：实现CE 设备在USB与PC连线的情况下显示为 移动设备（U盘）的功能！ 因为我的BSP中的usb function的driver只有serial的功能 无法通过简单的注册表更改实现切换！所以不得不自己移植sb function driver！（我是从samsug 官方bsp下的usbfn 移植到当前BSP下，）因为他的release note 有说明：
  The USB Mass Storage Function driver was implemented.
The USB driver was updated to support the USB Mass Storage Function. And, the usbmsfn.dll was added in the files folder. So, it can support both the Serial and the Mass Storage Function Class.
【现象：】
用 usb view 软件查看CE DEVICE 得到如下信息：

1. 
   
2. /*
   
3. Device Descriptor:
   
4. bcdUSB:             0x0000

USBD的中断可以相应！ 但目前没有任何反应在PC端！

现在不知道该怎么排查和解决了？  请坛友帮忙！非常感谢！ 只有65分了

Sysintr 在驱动中直接静态指定的！ 是
#define SYSINTR_USBD (SYSINTR_FIRMWARE+12)
Q:多问下：SYSINTR_FIRMWARE的值具体是多少 是否指定！

LZ是用的哪个BSP？

1、Sysintr 不一定是静态给定的，一般是动态的，在map.c文件有其数组的定义的
2、SYSINTR_FIRMWARE在不同的BSP里面，可能也是不一样的。。。如果是用的YL2440A的话，应该是如下：
#define SYSINTR_DEVICES     8
#define SYSINTR_FIRMWARE    (SYSINTR_DEVICES+8)

#define SYSINTR_OHCI            (SYSINTR_FIRMWARE+1)  // 17

OK! i get it

那么 USB枚举失败 是在哪里出现问题了？

做起来有点麻烦！

BYTE bEpIrqStat = ReadReg(pContext, EP_INT_REG_OFFSET);
    BYTE bUSBBusIrqStat = ReadReg(pContext, USB_INT_REG_OFFSET);

这个读值 肯定是有问题的！
    经过处理过的地址是0x350000！  感觉很奇妙！
