Hmm, there's a dmesg line saying that:

  Feb 16 20:09:51 kobe kernel: Symlink: ums0 -> usb4.2.0.16

but there is no ums0 symlink in /dev:

  # ls -ld ums*
  ls: ums*: No such file or directory
  #

Maybe this is why moused fails to work when it is launched from devd.

That's the device name for the touchpad port.  The default devd.conf
file passes `ums0' to /etc/rc.d/moused start ... so it shouldn't matter.
