Ahhh that explains that bit.  In your previous emails, I don't think you
mentioned there were /two/ ums(4) devices when the external mouse was
attached.

Unrelated... it's probably because there is nothing physically attached
to the PS/2 port of the laptop.

hid_is_mouse() is failing to tell that your Synaptics USB HID device is
a mouse, but /only/ when there's no other USB (HID) device on that USB
bus (usbus0).  I suspect it has to do with the hid_get_item() warnings
about chopping stuff off.  I can't tell from the source code for
hid_get_item() (a 313-line function) why it's behaving that way, or why
a totally different HID device (Logitech mouse) causes it to behave
differently for this HID device (Synaptics touchpad).  I've added
freebsd-usb@ to see if they know what's going on.

What possessed the laptop manufacturer to hang the Synaptics touchpad
device off a USB 3.0 controller is beyond me... I have problems booting
FreeBSD off USB 3.0 mass storage devices.
