Hi,

I wish to develop a usb-hid device driver. I have the following
questions:

1) Should it be developed using WDF or WDM?

2) I am referring to the HID standard class. Is it enough as a
document to refer all the APIs that can be used for the above purpose?

3) I've downloaded the latest(as on May 06, 2008) DDK from microsoft.
Does it have any example codes that mention about USB-HID device
driver?

Please note that I am referring the following resources:

1) USB Complete
-Jan Axelson

2) Making USB Device Drivers Easier Using the HID Class
-Stuart Allman

3) Device Class Def for HIDs.pdf

I am particularly looking for the example code to do this.

Regards,
Embedded Boy

Let me be little more specific.

I wish to write an application which can communicate with and USB-HID
device connected to the host. Actually, the device is a microchip
Explorer16 board that will be connected to the host pc using usb
interface.

My understanding is:
- The windows OS already has USB-HID driver.
- This application will basically be calling certain APIs/
functions(specified in the Device Class Def for HIDs.pdf) to send data/
request and receive data/reply.
- I will also need to check the microchip board's data sheet to check
how it will communicate in such a scenario, with the host.

Please confirm whether my assumptions are correct or not and do share
with me if you see there is something to suggest.

And ofcourse, do respond to both the posts(above one and current one).

Thanks in advance :)

Embedded Boy

you do not need to write a driver at all, this can be done entirely in user
mode using the HID apis in HID.dll (HidD_xxx).

Thanks.

I am currently referring to the "hclient" demo source code located
under the hid folder in the WDK demo source code. This seems to
provide enough information.

I guess that should resolve the issue. Any comments?

hclient is a fine place to start
