我根据msdn更改了注册表设置 但当我连接到电脑,然后它显示usb没有recongnized /
我使用的设置如下:
; ============================================== =================================== [HKEY_LOCAL_MACHINE \ Drivers \ USB \ FunctionDrivers \ CompositeFN] “属性”= MULTI_SZ: “0x80的” “bcdDevice”= dword:0 “DefaultPrefix”= “CompositeFn_” “ManufacturerString”=“复合USB” “MaxPacketSize”= DWORD:40 “功率消耗”= MULTI_SZ: “0×00” “ProductString”= “CompositDriver” “SerialString”= “为0x22” “产品ID”= DWORD:233A “厂商ID”= DWORD:0001 “DefaultString”=“e-con Composite 驱动程序“
[HKEY_LOCAL_MACHINE \驱动\ USB \ FunctionDrivers \ Serial_Class]
“CompositeFn_DefaultString”=” ActiveSync的” “CompositeFn_FunctionClass”= DWORD:0A “CompositeFn_FunctionDescription”=“USB ActiveSync的” “CompositeFn_FunctionProtocol”= DWORD:FF “CompositeFn_FunctionSubclass”= DWORD:00 ; “CompositeFN_DisableIAD”= DWORD:1
[HKEY_LOCAL_MACHINE \驱动\ USB \ FunctionDrivers \ Mass_Storage_Class]
“CompositeFn_DefaultString”=“ASI DataMyte海量存储“ “CompositeFn_FunctionClass”= DWORD:08 “CompositeFn_FunctionDescription”=“USB 大容量存储” “CompositeFn_FunctionProtocol”= DWORD:FF “CompositeFn_FunctionSubclass”= DWORD:00
[HKEY_LOCAL_MACHINE \驱动\ USB \ FunctionDrivers \ CompositeFN] “ClientDriverList”= MULTI_SZ: “Mass_Storage_Class”, “Serial_Class” [HKEY_LOCAL_MACHINE \ DRIVERS \ USB \ FunctionDrivers] “DefaultClientDriver”= “CompositeFN”

操作系统映像中的实际驱动程序是什么?插入设备时调试端口出现了什么?通过KITL与Platform Builder连接将是一个很好的下一步,因为您可以逐步完成整个驱动程序初始化代码路径。
