Hi All.

I am using wdf to make a usb dfu driver. Trying to reset USB device through
the call of WdfUsbTargetDeviceResetPortSynchronously or
WdfUsbTargetDeviceCyclePortSynchronously I see in the trace that both of them
reset device twice. That behavior prevents dfu from proper work.

Is it made intentionally? Or am I wrong? How to reset device just single
time using wdf?

Thanks, Stanislav.

If a reset is being sent twice, it has nothing to do with KMDF. It would
have
to be in the usb core. WdfUsbTargetDeviceResetPortSynchronously just sends
a
IOCTL_INTERNAL_USB_RESET_PORT, WdfUsbTargetDeviceCyclePortSynchronously
just
sends a IOCTL_INTERNAL_USB_CYCLE_PORT. Both of these functions just send
the
IRP once.

What OS and what host controller are you seeing this on? Are you sure that
you
are not calling WdfUsbTargetDeviceResetPort/CyclePortSynchronously twice in
2
different threads? In which callback(s) are you making the call to these
DDIs?

Hi Doron,

Thanks for reply.

The behavior is observed on the Windows XP SP1. I see it on both USB 1.1 and
2.0.
In the USB trace I see
Suspend
Reset
Get Descriptor
Reset
Set Address
Get Descriptor
Get Descriptor
and so on...

The time between two reset packets is small, less than 100 milliseconds. So
if DFU DETACH request is accepted and DFU mode is activated, the second reset
puts device back into Run-Time mode.

---

The code for device reset is actually very simple and I am sure it is called
just once.

VOID
EventIoDeviceControl(
IN WDFQUEUE Queue,
IN WDFREQUEST Request,
IN size_t OutputBufferLength,
IN size_t InputBufferLength,
IN ULONG IoControlCode
)
{
WDFDEVICE device = WdfIoQueueGetDevice(Queue);
PDEVICE_CONTEXT pDeviceContext = GetDeviceContext(device);
size_t bytesTransferred = 0;
NTSTATUS status;
WDF_USB_CONTROL_SETUP_PACKET controlSetupPacket;

UNREFERENCED_PARAMETER(InputBufferLength);
UNREFERENCED_PARAMETER(OutputBufferLength);

switch(IoControlCode)
{
case IOCTL_USBXDFU_RESET:
{
KdPrint(("IOCTL_USBXDFU_RESET\n"));

status = WdfUsbTargetDeviceCyclePortSynchronously(
pDeviceContext->UsbDevice
);
if (!NT_SUCCESS(status))
{
KdPrint(("RESET failed.\n"));
break;
}
}
break;
default:
status = STATUS_INVALID_DEVICE_REQUEST;
break;
}

WdfRequestCompleteWithInformation(
Request,
status,
bytesTransferred
);
}

Thanks, Stanislav.
