When I build the driver which I wrote based on 32bit computers and on 64bit computers. I came across these errors:

c:\winddk\driver\dispatch.obj : error LNK2001: unresolved external symbol __im p_USBD_GetUSBDIVersion

c:\winddk\driver\usb.obj : error LNK2001: unresolved external symbol __imp_USB D_ParseConfigurationDescriptorEx

c:\winddk\driver\usb.obj : error LNK2001: unresolved external symbol __imp_USB D_CreateConfigurationRequestEx

c:\winddk\driver\objchk_win7_amd64\amd64\usbcalc.sys : error LNK1120: 3 unresolved externals

It's strange because I used DDK build environment instead of VS2008, so can anyone point me in the right direction on how to fix this.

Is it because the functions can't be used in WIN7 OS?

Make sure you include usbdlib.h and if building in visual studio (i.e not manually through cmd)check that the configuration is good.

yeah.and now i use VS2008 to compile the driver , i got the error is :no target architecture. do u know how to solve this one?

well your configuration of the VS is probably bad, i suggest you try to compile it manually using the DDK build environments depending on which architecture your targeting (i.e if you are going to use this driver on a windows server 2003 x86 use the respective environment).
In command line you need to specify Usbd.lib as Linker input.
I guess this will resolve your problem.
