Hi

In my Windows Mobile, bsp_usbfn.dll(usbfn.dll) is the USB
function controller driver. It's registered in
\Drivers\BuiltIn\Usbfn, and loaded when system is booted.

call CreateBusAccessHandle(), and then call GetParentDeviceInfo()
I can get some information about usbfn.dll

ddi.dwSize:1584
ddi.hDevice:383680
ddi.hParentDevice:213120
ddi.szDeviceKey: Drivers\BuiltIn\Usbfn
ddi.szLegacyName: UFN1:
ddi.szDeviceName: $device\UFN1
ddi.szBusName: $bus\BuiltIn_0_1_0


I want to get the MDD function table UFN_FUNCTIONS.
Could you please give me a little advice?

thanks in advance

mike

The following table shows the functions that USB function client drivers
implement.

lpRegisterDevice
lpStart
...
lpSendControlStatusHandshake

-- from MSDN


but on the contrary UfnInitializeInterface in the source code
E:\WINCE600\PUBLIC\COMMON\OAK\DRIVERS\USBFN\
shows that usb function client drivers get UFN_FUNCTIONS from ufn bus
driver's mdd part, not put UFN_FUNCTIONS into ufn bus driver's mdd part.


put into mdd or get from mdd? could anyone give me some advice, which one is
correct?

You should call UfnInitializeInterface get these UFN_FUNCTIONS.
