wince(PXA255)下的USB ActiveSync添加U盘功能
我希望将wince(PXA255)下的USB驱动添加一项功能,它原本是ActiveSync和串口的.我想通过设置参数将它改成支持U盘(将PDA中的flash当做U盘用)和ActiveSync,串口的device设备.现在差不多了,U盘部分的协议已经跑起来了，就差Read Write ,format这三个命令了,台式机上能看到U盘的图标,可是read命令总是出错.附件是抓下来的数据,求达人指点原因,不盛感谢,愿意以这部分USB驱动的源吗相送，谢谢!

另外，我有pxa255使用USB下载的eboot,使用U盘协议，无需安装驱动,包括PC机器端的上位机程序.如能解决上述问题，或建议，一起奉送

这个想法不错,简单的说就是把USB serial和USB MASS STORAGE两个驱动的功能合二为一,在加个界面可以进行切换选择.不错,我试试,我现在是做了个应用程序来切换这两个驱动的,添加USB SERIAL和USB MASS STORAGE,默认是USB SERIAL,作为ACTIVE SYNC连接用,然后启动我的应用程序来完成二者之间的切换,每切换一下,把USB CABLE插拔一下就可以了.最终极的做法就是你提到的,把三者做到一块去.

终于等到一位大侠了,我现在已经能实现三者的功能合在一起了,切换功能正如你所讲.现在有了新问题.我的Pxa255使用Truffs来管理Flash,我的想法是当做为U盘时，PDA和host都能访问flash里面的文件.可是host管理flash是fat文件系统,而Truffs有自己的管理方法,请问有什么方法能让他们都能识别,你是怎么做到的?

我的系统不使用TRUEFFS，我做U盘的不是终端上的FLASH，而是插在终端上的SD卡，所以不存在你那个问题，我是想ACTIVE SYNC只有调试开发时使用，出产的设备只具备访问SD卡的做U盘的功能，不期望用户能看到NAND FLASH上的内容，我用的S3C2440平台。

我用PXA255，但是我也不用TRUEFFS，故也不会有这样得问题，PB已经不直接支持TRUEFFS，故MASS STORAGE你可能得做些改动。我使用IPSM，这个比较方便 ：）

所有的功能都实现了，现在wince运行后,PDA上显示是DiskOnChip,而USB连接到XP上后是个U盘,内容就是FLASH中的,
新问题是:如果wince修改了FLASH中的内容话,host这边显示的内容不变,必须插拔一下才可以看到更新的内容,而host修改了U盘内容的话,wince必须重新启动才能认识更改后的内容，谁又好办法解决这个问题.求高人指点 |

有什么办法让wince重新读一遍flash里面的文件,我发现如果直接读写物理扇区更新flash里面的文件的话，资源管理器怎么刷新都不能识别出FLASH里面更新的内容,除非重新启动才能识别,可是我想即时更新.

主机这边把这个分区DISMOUNT/MOUNT一下看看有没有作用.
我想请教一下你做这个的思路是怎样的,怎么着手去做,你把serial和U盘的驱动合二为一,增加一些冲突切换处理,最终也是生成一个驱动DLL文件,然后注册表里FunctionDrivers分别有Serial_Class和Mass_Storage_Class,只是它们的"Dll"键值都是这个新的驱动DLL文件.这个驱动文件导出函数里包括原来两个function的导出函数.是这样的吗? |

注册表里面的键值不用修改，增加一个模式设置键.将USB的驱动当作serial来用,在serial基础之上实现U盘协议,就是读串口，解析，发送，就完了.
使用Mount/UnMount的确能实现即时更新,代码如下: STOREINFO stinfo = {0}; PARTINFO partInfo = {0}; HANDLE hPart = INVALID_HANDLE_VALUE; BOOL CReadHardDiskDlg::MountUnmountFirstPart( BOOL fMount) { BOOL fRet = FALSE; if(INVALID_HANDLE_VALUE == hPart) { return FALSE; } if(fMount) { fRet = MountPartition(hPart); } else { fRet = DismountPartition(hPart); } return fRet; } BOOL CReadHardDiskDlg::InitStore() { HANDLE hstore; stinfo.cbSize = sizeof(STOREINFO); partInfo.cbSize = sizeof(PARTINFO); hstore = FindFirstStore(&stinfo); if (INVALID_HANDLE_VALUE == hstore) { return FALSE; } FindClose(hstore); hstore = OpenStore(stinfo.szDeviceName); if (INVALID_HANDLE_VALUE == hstore) { return FALSE; } if(FindFirstPartition(hstore, &partInfo) != INVALID_HANDLE_VALUE) { hPart = OpenPartition(hstore, partInfo.szPartitionName); } CloseHandle(hstore); return TRUE; } 只是这样一来,wince这边需要再运行一个小程序,我希望在U盘驱动里面调用这个函数，希望每个操作完毕的时候自动调用一下,这样就能自动即时更新了，可是如何知道更新动作完毕呢? 谢谢这位大侠,还望有更好的建议. |

是不是可以通知系统内容发生改变的标志呢 |

我是开了一个线程，U盘里写进新数据的时候,置一个跟新标志,拔下U盘的时候检测该更新标志,如果需要更新,就mount/unmount一下,您的方法应该更好一点,向系统发送什么样的消息，能让系统知道内容已经改变,谢谢,能不能说的明白点/

我修改了USB驱动,几乎能当作读卡器了,FLASH ,SD,CF都可以读写了
