Maybe the crash is in usb_keyboard?
I know that term/usb_keyboard.c assumes that there is exactly one USB
keyboard. It there is no USB keyboard, the code would crash because
usbdev is NULL. Also, the matching of the keyboard is incorrect. It
checks the device descriptor (even that code is a hack), but not the
interface descriptor.
