在5.0上实现通过USB device访问SD卡
大家好，我在PC端通过USB device可以访问到CE端的SD卡（不用activesync）,看到前面的帖子,CE本身的公共驱动oak/driver下USB驱动调用OpenStore函数打开了DSK1:,如下设置。
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\Mass_Storage_Class] "Dll"="usbmsfn.dll" "InterfaceSubClass"=dword:06 "InterfaceProtocol"=dword:50 "DeviceName"="DSK1:" "FriendlyName"="Mass Storage" ; idVendor must be changed. 045E belongs to Microsoft and is only to be used for ; prototype devices in your labs. Visit http://www.usb.org to obtain a vendor id. "idVendor"=dword:045E "Manufacturer"="Generic Manufacturer (PROTOTYPE--Remember to change idVendor)" "idProduct"=dword:FFFF "Product"="Generic Mass Storage (PROTOTYPE--Remember to change idVendor)" "bcdDevice"=dword:0 ; @CESYSGEN ENDIF CE_MODULES_USBMSFN 我的SD卡的注册表设置如下， ; SD Memory Storage class driver [HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Class\SDMemory_Class] "Dll"="SDMemory.dll" "Prefix"="DSK" "BlockTransferSize"=dword:40 ; send no more than 64 blocks of data per bus transfer ;"SingleBlockWrites"=dword:1 ; alternatively force the driver to use single block access ;"IdleTimeout"=dword:7D0 ; 2000 milliseconds ;"IdlePowerState"=dword:2 ; 0 == D0, 1 == D1, etc. ;"DisablePowerManagement"="" ; if value present, then disable (remove value to enable) "Profile"="SDMemory" "IClass"=multi_sz:"{A4E7EDDA-E575-4252-9D6B-4195D48BB865}", "{A32942B7-920C-486b-B0E6-92A702A99B35}" 我目前的困惑是我的SD卡的Prefix是DSK，又不是DSK1，系统是如何关联他们的，现在我想再打开一个设备（如第二个SD卡），我的Prefix应该设为多少？在什么地方设置。 谢谢！ |

呃 是只要 注册表加上这条 就能实现吗？我这边接上电脑后，能检测到，但就是盘符半天不出来！！！！ 会是哪里出问题呢？~？

楼主，不一定要是DSK1啊，如果你前面还有一个DSK，SD就变成了DSK2，这个要根据自己的情况来设定，目的是得到szDeviceName这个，OpenStore时候要用的，
搭车问一下：有没有做过Multi-Lun的朋友？device端除了在 bmRequestType = a1,bRequest = fe,wIndex = 0, wLength=1,wValue =0 回应1（我是两个），还需要做什么？我的情况是这种情况下PC发过来的CBW还是只有lun=0？ |

呃……加了啊……他是等很久很久才出来盘符，如后访问不到里面，也看不到属性……

找到干这个的组织了啊
俺是在4.2上搞的 不像5.0上啥啥注册表的全没有 已经基本（因为Write10还没写完）实现了访问SD卡功能， 现在就是想搞个再把nand flash也开放的功能 也跟werna兄有同样的困惑啊 除了get max lun回复1外，还需要做什么？怎么让PC那边来读两个MBR呢？ SD卡一个nand flash一个 |

我是要读两个SD卡，我在我的板子上面实现了双SD卡的功能，通过测试，我确定这两个设备一个是DSK1:,一个是DSK2:,
然后按照以前帖子的回复，我在public/oak/driver/usbfn/class/storage/scsi2/block.cpp下面修改Store_init的代码，g_hStore = OpenStore(g_szDeviceName);是实现打开store的地方，注册表默认是打开DSK1:，然后我自己在后面加注了OpenStore(“DSK2:");想实现打开DSK2:，并且通过调试，好像OpenStore(“DSK2:");成功了，但是编译完成后，连接PC,还是只能看到一个盘（DSK1:），大家可否给我一个思路，如何让PC端认到我的DSK2. 多谢 |

光是多OpenStore一个还不行哦
我现在是想不明白怎么让PC知道你这边有两个SD卡，如何让他发两个read10来读MBR |

理论上PC Get Max Lun以后，PC就知道有几个了，但是我的问题它不发lun=1 的CBW下来？？郁闷了

微软的驱动只支持一次EXpose一个设备给USB HOst,除非你自己修改驱动

收到Get Max Lun后，我wince这边直接回复的0x00。。。
回复0x01也一样 我没感觉到有啥区别啊 请教werna兄 lun=1 的CBW的operationcode是多少啊？ 还有我的usb现在读SD卡速度还能接受，写SD卡速度简直根蜗牛一样，SD卡驱动是木有问题的，应该还是在USB这块，怎么把速度提高啊 我USB的in和out都没用DMA的 可是一个速度是M/S 一个是K/S，这个差距也太大了 |

请问，设备的Lun ID在何处设置？而后如何将请求发向不同的SD设备呢？
