have an HID device that spews mouse messages. Under some circumstance those mouse message need transformed to Keyboard special keys. I need this to work for all versions of windows from 7 (or earlier) on.
I thought this would be a relatively simple filter driver. But I have not worked with Windows drivers in a long time
Reviewing documents suggests this is not as trivial as I thought.
Am I even pursuing the right approach ? Can this be done in userspace - apparently SendKeys() can inject keyboad commands. Can I trap the mouse in userspace ?
From what I see an HID filter driver is not an option until Windows 10 and highly discouraged.
I am finding it hard to beleive that a task that is maybe 20 lines of C inside an embedded device is impossible in windows.
Look at the moufiltr example. This will let you see all mouse input for the hid of your choice. You would then have the same driver filter the keyboard stack (copy the code from kbdfiltr) which allows you to inject keystrokes

The limitation of SendInput is that it only works for the current session. You can’t use it for the security desktop. It might have IL restrictions too
