### USB Mouse

NTDEV
1

Hi Folks,

Is there a way to send a command to a USB mouse?

I am planning on designing something that would look just like a HID USB
Mouse, but I would like to support some calibration commands and lights/etc
on this “mouse”.

Is there some windows API/etc that can I use to send a command to my custom
mouse so that I could have the processor in the mouse flash lights/etc?

Thanks

Expose a 2nd top level HID collection which has the necessary reports
for your custom data. The actual mouse itself is not openable since the
OS opens it for exclusive access.

Yes, but there’s one bit of trickiness: Windows opens pointing devices
and keyboards exclusively, so your app that wanted to send commands to
it wouldn’t be able to open the device. One way around that would be to
have your device report 2 HID Top Level Collections, one of which is the
mouse, and the other of which has vendor-specific output reports defined.

Another way around it would be a HID filter driver, but that’s not for
the faint of heart.

Hi,

Thanks for the fast reply!

So you mean I should have my processor respond as both a USB HID Mouse + a
secondary device? I could then directly open a channel to the secondary
device and issue commands?

No, HID has its own abstraction of top level collections (TLCs) of data.
You will enumerate as one device. The HID class driver will enumerate 2
children, one for the mouse, one for your vendor data. If you are
unfamiliar with HID TLCs, you should read the HID spec before proceeding
any further…

Add the second HID collection to your mouse’s firmware, then send the HID
reports to it from user mode using HID API.
