Hi All,
I have a USB Client Driver which uses Mouse Class Service.Basically I
have got a .inf file,in which i have specified Mouse Class as the service
installer for my USB Device.The problem is I don’t receive IOCTLS from the
Application.The Error Code which the application receives on issuing
DeviceIoControl is 1(ERROR_INVALID_FUNCTION).I have checked for the
registration of IRP_MJ_DEVICE_CONTROL in my driver.Can any body please let
me know why does the application receive this ?.
Thanks.
Best Regards,
Sai Prasad

Mouclass does not allow random IOCTLs down the stack; if you are using
HID, you are better off creating a 2ndary top level collection whose
features correspond to your IOCTLs and communicating to your driver this
way.

Hi Doron,
Actually I am not using HID.Is there any way by which I can make the
application target the IOCTL’s directly to my driver.
Thanks.

create a 2ndary devobj in your driver that is not attached to the pnp device stack (ie, you just make another call to IoCreateDevice in start device). this devobj must have a name and a symbolic link associated with it; you cannot use a device interface for the 2ndary devobj b/c you need a PDO for that. After that, you must route irps appropriate in each dispatch function (you will even get PNP irps to the non PNP devobj to find target relations). The usual method of doing this is sharing a common header between both device extensions and a field in the header indicates the type of devobj the IRP is destined for.
