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.
