In addition to doing that, you can also check that it really works (actually simulate a keystroke and see if it appears in the keyboard buffer or not).

My USBKEYB program includes an external API for simulating keystrokes with the /K method. You can check for that API, and if it exists, use it to simulate the keystrokes via scan codes so you don't have to do it yourself. Indeed it is a can of worms, but a necessary one to open if there is any hope of creating a usable DOS USB keyboard driver.

Also as an FYI, the next version of USBMOUSE will include a similar API to simulate/virtualize mouse movements and button presses.
