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

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.


Hi,

Does your mouse only fail to work in X-org, or also the console?

Run "usbdump -i usbusX -f Y -s 65536 -vvv" to catch USB events for ugenX.Y. That might give some further clues.

If using X.org, do you use hald or devd backend?
