MOUSE_APPLETOUCH selects USB and depends on USB_ARCH_HAS_HCD. That's
actually quite a common pattern.

But what is the purpose of USB_ARCH_HAS_HCD? It is set by default if
USB_SUPPORT is set. And USB depends on it, but since USB also depends on
USB_SUPPORT that seems superfluous.

My slow day continues, because I find this hard to grok.
