Yes, if nothing else than the sheer volume of code. With KMDF, you don't
have to write any power or PnP code at all.

Thanks,

I just began writing of driver. For the moment, it's just dialog
through Control Endpoint.

I have two remarks :

1) It's not so easy to use WDF because it's a whole new (for me)
syntax. GoodBye all habits.
2) In one day I was able to dialog with my device trough Control
Enpoint and without writing any PNP or Power Management code (well
beside AddDevice, PrepareHardware, ...)

All in all, i'm pretty impressed by WDF.

Fred.

Hi,

I need a sample code for WDF driver which read data from isochronous pipe.
Can anyone please help as I am begineer to the driver development work.

I followed the steps given by Mr. Doron,

> the WDFREQUEST. You would allocate the memory for the URB using
> WdfMemoryCreate, format the fields, call
> WdfUsbTargetPipeFormatRequestForUrb() and then call WdfRequestSend

but I am getting STATUS_INVALID_PARAMETER as soon as WdfRequestSend is
executed.

Take a look at the src\kmdf\USBSAMP in the Vista RC1 WDK. It shows how to
talk to isoch endpoints.

Hi Eliyas,

Please let me know from where I can download Vista RC1 WDK, I couldn't
find it in microsoft website. It would of great help if you can give me the
path.

Thanks,
Gopalakrishnan.
