in my opinion, Windows' implementation of USB is fundamentally broken.
It's a mouse, you stupid computer! You shouldn't need to spend a minute
or more installing a new device driver for it! And you shouldn't need to
install the driver yet again if I poke it in a different hole than I did
last time! Every other ******* OS on the planet is smart enough to say
"Oh, a mouse! I know how to use those!" within a handful of milliseconds!

Here's a cute gotcha I hit this week:

- Have a running Windows 8.1 machine with PS/2 keyboard.
- Shut it down, start up with only USB keyboard.
- Shut down and boot again with PS/2 keyboard atached.
- Windows ignores it (although BIOS flashes lights normally, etc).
- Registry change (found by google) & reboot brings it back to life.

Can't imagine how many good keyboards were dumpster'd over that one.
