i have write virtual PDO device, for which WinUsb attached as low filter (and then FDO by umdf driver). my PDO basically handle different IOCTL_INTERNAL_USB_SUBMIT_URB requests (URB_FUNCTION_GET_DESCRIPTOR_FROM_DEVICE, URB_FUNCTION_CONTROL_TRANSFER, URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER, etc)
umdf depending on the vid/pid of my device send data to me or via WinUsb_ControlTransfer or via WinUsb_WritePipe and WinUsb_ReadPipe. in case WinUsb_ControlTransfer all is ok. i got URB_FUNCTION_CONTROL_TRANSFER request in self PDO. but WinUsb_WritePipe (in user mode from winusb.dll) is always fail with STATUS_INVALID_PARAMETER. as i research - request request reaches WinUsb_WritePipe function inside winusb.sys in kernel and here fail on call WinUSB_IsInterruptOrBulkOutPipe - it return false for my endpoint and as result WinUsb_WritePipe function return STATUS_INVALID_PARAMETER
the PipeID (view in debugger) is correct and corresponds to my (USB_ENDPOINT_DESCRIPTOR.bEndpointAddress & USB_ENDPOINT_ADDRESS_MASK) and this is BULK , DIRECTION_OUT endpoint (so all correct), but how i view in code of WinUsb_WritePipe - pointer to object object was in internal structure for my endpoint. and this pointer is 0. because this WinUSB_IsInterruptOrBulkOutPipe return false. but i can not found - where and when this object created for endpoint and why it not created for my bulk endpoints. may be i wrong fill USB_CONFIGURATION_DESCRIPTOR ? or why this happens ? why winusb.sys not allocate some data for my endpoints ? but in this case WinUsb_ControlTransfer is work ? i fill USB_CONFIGURATION_DESCRIPTOR in next way
