请教USB驱动编译问题

我在调用PUSB_INTERFACE_DESCRIPTOR pid = USBD_ParseConfigurationDescriptorEx(pdx->pcd, pdx->pcd, 0, 1, -1, -1, -1);时总出现这样的编译问题Dispatch.obj : error LNK2001: unresolved external symbol \"__declspec(dllimport) struct _USB_INTERFACE_DESCRIPTOR * __stdcall USBD_ParseConfigurationDescriptorEx(struct _USB_CONFIGURATION_DESCRIPTOR *,void *,long,long,long,long,long)\" (__imp_?USBD_Pa
rseConfigurationDescriptorEx@@YGPAU_USB_INTERFACE_DESCRIPTOR@@PAU_USB_CONFIGURATION_DESCRIPTOR@@PAXJJJJJ@Z)
Debug\\Driver.SYS : fatal error LNK1120: 1 unresolved externals

望高手指教
