wince 6.0 使用usbser.dll实现usb转串口，UsbAttachDevice错误，求指点！！
wince平台下利用源码的usbser.dll开发一款usbs转串口的打印机设备。UsbAttachDevice返回值错误，failure message
Drivers\USB\LoadClients\1155_22336\Default\10USBD:ConvertToClientRegistry, Registry Drivers\USB\LoadClients\1155_22336\Default\10 is exist

USBD: Calling client attach proc:? M???
USBD: Calling client attach proc for USBSER_CLASS
Enter the callback function

m_hDriver=0,RegPath=Drivers\USB\ClientDrivers\USBSER_CLASS
After Get Path
-UsbClientDevice::Init return 0Finished the callback function
USBD: Client did not accept control of device
注册表设置如下：
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1155_22336\Default\10\USBSER_CLASS]
"Prefix"="COM"
"Dll"="usbser.dll"
[HKEY_LOCAL_MACHINE\Drivers\USB\ClientDrivers\USBSER_CLASS]
"Prefix"="COM"
"Dll"="usbser.dll"
"DeviceArrayIndex"=dword:1
"RxBufferSize"=dword:4000
"IClass"="{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}"
请问是注册表设置错误吗，求大牛指点！！

[解决办法]
既然是转串口，转换后的串口信息是不是不全啊
[解决办法]
你这打印机是指本身CE就是打印机还是CE连接另外一台打印机
CE是做主还是做从
[解决办法]
"Prefix"="COM"
"Dll"="usbser.dll"
"DeviceArrayIndex"=dword:1
这里会不会直接打开真正的串口设备了呢？
而没跑到 USB 的驱动啊？
