X220 loses keyboard when Logitech USB wireless adaptor is unplugged

Hi,

I just got this from /var/log/messages:

As you can see, I took the adaptor connected to ugne0.3 out. In
addition, the keyboard ukbd0 was disconnected too. When I put the
adaptor back in, the keyboard comes back too. As you can imagine, it is
a bit hard to unplug the built-in keyboard on a notebook.

uname -a says:

FreeBSD X220.ovitrap.com 10.0-CURRENT FreeBSD 10.0-CURRENT #23: Sat Feb

Any thing I could do to help fix this?
