If I start FreeBSD without the external receiver and run udo usbconfig -d ugen0.3 dump_curr_config_desc, I get the following output:
ugen0.3: <product 0x2970 vendor 0x06cb> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

Now, if I plug in the receiver and reboot my computer (the touchpad does not work in FreeBSD unless I start the computer with that device plugged in -- the external mouse that came with the receiver works just fine without a reboot) and then run the same command again (note that when booting with the external device plugged in, according to "lsusb", the Symantec touchpad changes from ugen0.3 to ugen0.4), I get the following:
Output of lsusb:

With that device plugged in during the booting process, I'm able to do a left tap/click and a right click with the touchpad. Scrolling does not work unless I use the external mouse instead of the touchpad.
If I now decide to unplug the external device, the touchpad works until the next reboot.
