I couldn't find any already made tools for this, so I've been playing
around with c and libusbhid to examine the keyboard/mouse combo and I
think I've figured out the problem. This wireless combo appears as just
a simple device with one interface (I think) and the report for the
mouse and keyboard are combined together. Does freebsd support having
keyboard and mouse events in the same report? If not, could I do
something like catch all the events through uhid0 and inject them back
into the kernel from a user-space program? The mouse is probably pretty
simple due to moused, but I don't know how I'd inject the keyboard

I sense much NT in you.
NT leads to Bluescreen.
Bluescreen leads to downtime.
Downtime leads to suffering.
NT is the path to the darkside.
Powerful Unix is.
