Okay try the 'dump_curr_config_desc' command to usbconfig(8):

     usbconfig -d ugen0.3 dump_curr_config_desc

For my Areson USB mouse, this reports:

$ sudo usbconfig -d ugen0.2 dump_curr_config_desc
ugen0.2: <USB Device Areson> at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps)
pwr=ON (100mA)


 Configuration index 0

    bLength = 0x0009
    bDescriptorType = 0x0002
    wTotalLength = 0x003b
    bNumInterfaces = 0x0002
    bConfigurationValue = 0x0001
    iConfiguration = 0x0000  <no string>
    bmAttributes = 0x00a0
    bMaxPower = 0x0032

    Interface 0
      bLength = 0x0009
      bDescriptorType = 0x0004
      bInterfaceNumber = 0x0000
      bAlternateSetting = 0x0000
      bNumEndpoints = 0x0001
      bInterfaceClass = 0x0003  <HID device>
      bInterfaceSubClass = 0x0001
      bInterfaceProtocol = 0x0002
      iInterface = 0x0000  <no string>

      Additional Descriptor

      bLength = 0x09
      bDescriptorType = 0x21
      bDescriptorSubType = 0x00
       RAW dump:
       0x00 | 0x09, 0x21, 0x00, 0x01, 0x00, 0x01, 0x22, 0x59,
       0x08 | 0x00

     Endpoint 0
        bLength = 0x0007
        bDescriptorType = 0x0005
        bEndpointAddress = 0x0081  <IN>
        bmAttributes = 0x0003  <INTERRUPT>
        wMaxPacketSize = 0x0008
        bInterval = 0x000a
        bRefresh = 0x0000
        bSynchAddress = 0x0000
...


I'm looking for an "Interface #" section with "bInterfaceClass = 0x0003 
<HID device>" and "bInterfaceProtocol = 0x0002" lines (class 0x3
protocol 0x2 is a mouse, supported by our ums(4) driver).  If you have
that, then it should work "out of the box" with moused(8) configured
with the "auto" protocol (required for USB pointing devices).

You didn't say whether the touchpad works with another USB mouse
attached or not.  I wouldn't expect plugging a different mouse in to
have any effect on the touchpad behaviour, but if so, please also run
the above usbconfig(8) command:

  - with no external USB mouse plugged in, targetting the Synaptics
touchpad device (ugen0.3)
  - with an external USB mouse plugged in, once for the Synaptics
touchpad device (ugen0.3) and once for the external mouse (ugen?.?)

Thanks,
Anthony
