Title:
  device_add usb-hub causes segfault in qemu-1.0

Status in QEMU:
  Fix Released

Bug description:
  When calling the command

  (qemu) device_add usb-hub,bus=usb.0,port=4

  qemu replies

  Error: usb port 4 (bus usb.0) not found (in use?)

  Then qemu crashes with a segfault:

  [ 1546.177627] qemu-system-x86[1710]: segfault at 0 ip b75d3f8b sp
  bfddb0b0 error 6 in qemu-system-x86_64[b7488000+2e2000]

  Maybe it might be related to the docs/usb2.txt where UHCI has only 2
  ports. But a mistake in the port number should not cause qemu to crash
