There is a fixme next to the printf statement in 
drivers/usb/host/uhci-hcd.c

  1886                  if ((status & USBSTS_HCH) && !uhci->is_suspended) {
  1887                          err("%x: host controller halted. very bad", io_addr);
  1888                          /* FIXME: Reset the controller, fix the offending TD */
  1889                  }

The quickcam source isn't available to fix the null dereference bug.
