It fails in both X-org and console.
In X, recently I've only been using devd.
When trying to use the command usbdump -i usbus0 -f 3 -s 65536 -vvv on my touchpad (without any external usb receiver connected), nothing happens at all. No left-click, no right-click, nothing. 

However, if I insert an external USB receiver and then reboot the computer, the touchpad works just fine in both console and in X-org.
If I now do the command above, since I've connected the receiver and done the reboot, I get the following output (just note that during the reboot, the address of the touchpad was changed from ugen0.3 to ugen0.4):
