I have to write a WIA user-mode driver (so a *.dll) and I have to use an
existing kernel-mode driver (usbscan.sys) in order to communicate with the
device.

Where can I find a guideline?

Thank you!

Starting point is possibly the Windows Driver Kit documentation.

Also the blog contains usefull information and link:

No, that doesn't have anything to do with either usbscan.sys or WIA.

Where have you looked?

A WIA minidriver is not particularly hard, but there are a lot of routines
to fill in. The samples are a good start.

Thanks for your answers.

I am studying the "wiascanr" minidriver sample.
I read the "USB Driver" in "Imaging Devices" from the WDK.
I saw the CreateFile and an example of the DeviceIoControl.

I will make some research on I/O control codes... But it would be great if I
find a guideline for the use of ReadFile/Bulk IN, WriteFile/Bulk OUT in order
to receive or send data to a real device, not the fake device of the sample.
