【usb 总线枚举失败！《usb function driver》问题如何排查！】

sypanyue 2009-12-25 21:53 楼主

【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：

/*
Device Descriptor:
bcdUSB: 0x0000
bDeviceClass: 0x00
bDeviceSubClass: 0x00
bDeviceProtocol: 0x00
bMaxPacketSize0: 0x00 (0)
idVendor: 0x0000
idProduct: 0x0000
bcdDevice: 0x0000
iManufacturer: 0x00
iProduct: 0x00
iSerialNumber: 0x00
bNumConfigurations: 0x00
ConnectionStatus: [color=#FF0000]DeviceFailedEnumeration[/color]
Current Config Value: 0x00
Device Bus Speed: Low
Device Address: 0x00
Open Pipes: 0
*/

DeviceFailedEnumeration 说明是枚举失败了！

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！

看了下！ USB的插拔事件是由线程ISTMain(监控的！

// interrupt service routine.
static
DWORD
WINAPI
ISTMain(
LPVOID lpParameter
)
{
RETAILMSG(1, (TEXT("usb->enter interrupt sevice routine.\r\n")));
SETFNAME();
FUNCTION_ENTER_MSG();
PCTRLR_PDD_CONTEXT pContext = (PCTRLR_PDD_CONTEXT) lpParameter;
ValidateContext(pContext);
CeSetThreadPriority(pContext->hIST, pContext->dwISTPriority);
while (!pContext->fExitIST) {
pContext->fRestartIST = FALSE;
// Enable Suspend Mode in the Power Register
// SetClearReg(pContext, PWR_REG_OFFSET, SUSPEND_MODE_ENABLE_CTRL, SET);
// Disable All Endpoint interrupts
WriteReg(pContext, EP_INT_EN_REG_OFFSET, 0); // Disable All
// Enable Device interrupts
WriteReg(pContext, USB_INT_EN_REG_OFFSET, (USB_RESET_INTR));// | USB_SUSPEND_INTR));
// Enable Endpoint interrupt 0
EnableEndpointInterrupt(pContext, 0);
while (TRUE) {
DWORD dwWait = WaitForSingleObject(pContext->hevInterrupt, INFINITE);
if (pContext->fExitIST || pContext->fRestartIST) {
break;
}
if (dwWait == WAIT_OBJECT_0) {
HandleUSBEvent(pContext);
InterruptDone(pContext->dwSysIntr);
}
else {
RETAILMSG(ZONE_INIT, (_T("%s WaitForMultipleObjects failed. Exiting IST.\r\n"),
pszFname));
break;
}
}
RETAILMSG(ZONE_INIT, (_T("%s now Send detach, moved code for reset interrupt +chandolp+ .\r\n"), pszFname));
// Send detach, moved code for reset interrupt +chandolp+
pContext->pfnNotify(pContext->pvMddContext,
UFN_MSG_BUS_EVENTS, UFN_DETACH);
pContext->fSpeedReported = FALSE;
pContext->attachedState = UFN_DETACH;
pContext->isattachedusbcable = FALSE;
// Disable Device interrupts - write Zeros to Disable
WriteReg(pContext, USB_INT_EN_REG_OFFSET, 0 );
// Disable endpoint interrupts - write Zeros to Disable
WriteReg(pContext, EP_INT_EN_REG_OFFSET, 0);
// Clear any outstanding device & endpoint interrupts
// USB Device Interrupt Status - Write a '1' to Clear
WriteReg(pContext, USB_INT_REG_OFFSET,
(USB_RESET_INTR | USB_RESUME_INTR | USB_SUSPEND_INTR));
// End point Interrupt Status - Write a '1' to Clear
WriteReg(pContext, EP_INT_REG_OFFSET, CLEAR_ALL_EP_INTRS);
}
FUNCTION_LEAVE_MSG();
return 0;
}

但 pContext->pfnNotify(pContext->pvMddContext, UFN_MSG_BUS_EVENTS, UFN_DETACH);没有调用

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

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！
